078 manual onoff type control system with deadband
现在让我们研究死区位置控制的控制艺术。
All right now let's study the art of control to position control over deadband.
我们知道，在控制艺术中，我们有一个缺点，那就是它有不必要的恐惧和恐惧，这意味着你有时会感觉到沃尔维斯在上下。
We know that in the art of control we have a disadvantage that it has needless fear and terror which means you're feeling Walvis getting on and off at times.
所以这有点奇怪，因为每个设备都会在开启和关闭时间上产生老化效应，你知道。
So it's kind of weird entered because every device has an aging effect on and off times you know.
因此，您一天内会多次打开和关闭设备。
So you go on and off the device multiple times in a day.
所以它可能很快就会损坏。
So it may get damaged very soon.
你需要更换它。
You need to have to replace it.
好的。
OK.
所以对于怀特来说，在某种程度上我们使用死蝙蝠。
So to White that for a certain extent we use a dead bat.
好吧，也就是说，整个范围的 0.5% 到 2% 的日期是作为一般范围引入的，您也可以增加或减少它。
OK so say is a date of 0.5 to 2 percent of the full range is introduce this as a general range you can also increase or decrease it.
这个死区也被称为差异间隙或 Nutans on。
And this deadband is also known as differentia gap or nutans on.
所以在这个中立区发生的事情没有任何控制行动。
So what happened in this neutral zone there is no control action.
好吧，假设您将室温控制在 20 度，并且您希望温度在 20 到 25 之间。
Ok suppose you are controlling a room temperature to 20 degree and you want that if the temperature is between 20 to 25.
你不想要任何你对此感到满意的行动。
You don't want any action you are happy with that.
因此，在这种情况下，五度是死区。
So the five degrees are deadband in that case.
因此，在我们的示例中，我们再次以液位为例，我们有一个设定点，这是一个反馈模型。
So in our example let's take that take the liquid level example again we have a set point and this is a feedback model.
现在请注意这里发生了一些不同的事情。
Now notice something different happening here.
这个值就在这里。
This value is on here.
好的。
OK.
换颜色。
Change color.
该值在此亮起，并且设定值和反馈值小于设定值。
This value is on here and the value of setpoint and the value of feedback is less than setpoint.
您的感觉良好，但随后该值低于设定值。
Your feeling is on OK but then the value goes below setpoint.
这种感觉已经消失了，但在另一个地方又出现了。
The feeling is off it get on again at a different point just here.
所以这条线是它的一个新设定点。
So this this line here this is a new set point of it right.
你说我们正在打开液位并且液位低于新的设定点。
And you said point we're turning on the level and the level is below a new set point.
所以这件事又开始了。
So this is getting on again.
这就是填充物的价值所在。
So that's part the value is on the filling is on.
再次填充，此时感觉还不错。
And again this pide the filling is on and again at this point the feeling is on okay.
但如果你看到这里的死区在哪里。
But here if you see where is the deadband here.
这是这部分吗？我的意思是死区就是这个地方。
Is this part and I mean just again the deadband is the spot.
这里没有控制动作。
There is no control action here.
如果您注意到当值从该部分的设定点下降时，则没有控制动作。
If you notice when the value is dropping from set point of this part there is no control action.
这关了
This is off.
好的。
OK.
再次强调，如果您在这个位置看到这部分，那么上一个示例中并没有发生这种情况。
Again here if you see this part into this spot the value of this was not happening in the last example.
在上一个示例中，我们的控制操作发生在此时，但它一直停留在此时。
Our control action take place at this point in the last example but it's sticking at this point.
不，不是在这一点上再次在这一点上。
No not at this point again at this point.
你的感觉时好时坏，如果你看这里，我会设定一个点，但目前还没有开始。
Your feeling is on and it off I'd set point if you look at here but it is not getting on at this point.
所以这就是你已经死了，但此时你没有采取任何控制行动。
So that's part this is you are dead but you're not taking any control action at this point.
好的。
Okay.
再次低于该点，它再次陷入平局。
Again below that point it gets tied again.
所以特别是如果你注意到颜色的变化，那就说明这里有心思。
So particularly if you notice the change in color There's mind over here.
有那么糟糕吗。
Is it that bad.
这又是其中的一部分。
Again that's part that's part of that.
嘿，这里没有受控的行动。
Hey there's no controlled action here.
作为其中的一部分。
As part of this.
那么如何介绍乐队呢？
So how do introduce the band.
您可以想象，如果您延迟打开阀门，以便您可以及时看到这一点。
And you can imagine if you have a delay in turning on valve so you can see this on time.
还不到下班时间。
It's less than off time.
好的。
Okay.
如果这是一回事，则可能是 2.5 秒，因此您增加了打开墙壁的延迟。
If this is one thing this might be 2.5 second so you have increased the delay in turning on the walls.
因此，这减少了开关时间，延长了其寿命。
So this has this has decreased is ON-OFF time and this has increased its life.
因此，我们感觉坠落或多或少比使用死咬的类型有更多的时间来更好地操作帆船。
So we're feeling fall more or less have more time to operate the sailboat better than the on of type by it using a dead bite.
好的。
OK.
那么你是如何在下个月结束的逻辑中如此糟糕地使用这个的呢？
So how did you use this that bad in a logic that's over next month.
所以我们在这里有一个练习。
So we have an exercise here.
它说模拟液体标签控制与死区效果西门子 TIAA 满星。
It says simulate liquid label control with deadband in effect Siemens TIAA the full stars.
通过使用 SDL 控制校准杠杆传感器生成控制算法来读取 Tang 的反馈，但我使用的是 11 及以上。
Read the feedback of Tang by calibrating lever sensor generate on of control algorithm using SDL control but I'm using 11 and up.
所以我们需要一个独立的电位器来控制在我们的力量中遇到糟糕的一天显示错误的感觉。
So we need an independent potentiometer to control that had a bad day display error feeling in our forces the same thing.
现在让我们回到我们的软件。
Now let's go back go back to our software.
我创造了这个逻辑。
I have created this logic.
我将向您解释这是如何完成的。
I'm going to explain to you how this has been done.
这并不难，我们只需从逻辑上进行一些修改即可。
This is not so difficult we have just a few modification from on of logic.
因此，如果您现在在 ACLU 内看到 a c，则逻辑已被使用。
So if you see the a c now inside the ACLU the logic has been to use.
为什么。
Why.
因为这种感觉是通过淑女来发挥的。
Because via actuating this feeling was using ladylike.
这背后是有原因的。
There's a reason behind that.
原因是如果您注意到这部分 Viiv 的两个批次的输出。
The reason is if you notice this part Viiv on two lots the output.
好吧，此时早些时候发生了什么。
OK what was happening earlier and earlier stage at this point.
它要么是打开的，要么是关闭的。
It is either it was on or off.
你不必持有国家。
You don't have to hold the state.
但在这里我们必须保持状态。
But here we have to hold the state.
但我的意思是，如果你从这一点到这一点都在激发这种感觉，那么我们就必须保持这种状态。
But by that I mean if you are actuating the feeling here from this point to this point the feeling is on so we have to hold the state.
好的，填充开始，然后从这里消失，从这里到这里，感觉消失了，头发填充开始。
OK this is filling is on and then it goes off from here and from here to here the feeling is off and a hair filling is on.
这里填充已关闭。
And here filling is off.
因此，我们必须煮沸状态，以便当您需要设置或重置时，最好的方法是通过少量逻辑来完成。
So we have to boil the state so for that when you need to set or reset it's the best way is to do by little logic.
好吧，所以最后没有必要写出整个逻辑。
Ok so there is no compulsion to write the whole logic in the end.
您可以轻松地在 FBD 以及逻辑或 Iseult 中执行此操作。
You are comfortable to do it in FBD as well as the logic or Iseult as well.
好的，如果您注意到我在这里引入了一个新的可变死区显示。
OK so here if you notice I have introduced a new variable deadband display.
好吧，让我们回到第一家工厂。
Ok let's come back to first factory.
事实上我们有这一步。
In fact we have this step.
您可以通过旋钮来定义死区并显示其值，我们将其显示出来。
And you knob to define the deadband and to display its value we have it on display.
所以我们这里有两个新元素：电位计和显示器。
So we have two new elements here a potential meter and a display.
因此，如果我们去找驱动程序，我已将潜在的后视镜甲板连接回 81 或 8，并在 Judy 120 处按显示器连接甲板。
So if we go to the drivers I have connected the potential mirror deck back at 81 or 8 and deck by display at Judy 120.
如果您按照我的课程进行操作，那么可以让您快速参考。
OK just for you to have a quick reference if you're following me along with the lessons.
好的。
All right.
现在中央情报局回到他身边，所以这些价值观是理智的。
Now coming back to him CIA so these values are sane.
现在，如果您看到这里的死区显示，则显示等于除以火的一天。
Now if you see here deadband display display is equal to a day when divided by fire.
为什么我这么做。
Why I did that.
因为如果你注意到这里我的死区，这个配置衰减为零。
Because if you notice here my deadband this configuration is zero to attenuate.
好的。
OK.
在演示中我们刚刚读到标准值指向百分之五到百分之二。
And in the presentation we just read that the standard values point five to 2 percent.
好的，所以我需要从 0% 到 2% 的范围。
OK so I need the range from zero to 2 percent.
如果它为零，则意味着它没有这样做。
If it is zero then it means that it's doing it didn't.
所以我从零到骗子中取零到百分之二意味着零到两票。
And so I'm taking zero to 2 percent from zero to dupers means zero to two votes.
因此，零涉及意味着我必须将这个范围除以五，这样我才能获得零到两票。
So zero to do with means I have to divide this range by five so that I will get zero to two votes.
好的，所以我只是注意到它的范围标度，它不会在 2 到 因为我已将其除以 5。
OK so I'm just noting the range scale of it it wouldn't do it at 2 to for that I have divided this by five.
因此，州禁令显示已除以五。
So the state ban display is dead by divided by five.
好的。
All right.
现在，这个新设定点上的新设定点就是这个新设定点是设定点减去我们想要的绑定的值。
Now new set point on this new set point is what this new set point is the set point minus the but on which bind we want.
好的，新的设置将是设定点减去死区。
OK so the new set would be set point minus deadband.
所以这之间的事情太糟糕了。
So this thing between here is that bad.
如果你愿意，我可以用屏幕笔写字，这就是你。
If you want I can write can screen pen and this this is you.
这不仅是因为这个新的设定点自动是设定点减去债务。
This not only is so this new set point automatically is set point minus debt.
这就是我在这里所做的。
That's what I did here.
新的设定点并不完全是因为我的设定点部分是我的设定点。
New set point is not quite as my set point part is my set point.
这是我的设定点减去死区显示的部分。
This is the part this is my set point set point minus deadband display.
现在为什么我要显示，因为这个显示的范围是零到二。
Now why I took display because this display is in the range of zero to two.
所以在这里你会再次找到 10。
So again right here would lead you to 10.
好吧，所以你说把他的潜在回报减去两个字或零给我选择的任何东西。
OK so you said point his potential return minus two word or zero to whatever I choose.
这就是我的新闻点。
So this is my news point.
我不能收回这一点，我应该采取死区显示，因为如果我执行死区，该点的范围是 0 到 10，我可以将其放在这里。
I cannot take that back and I should take deadband display because if I do deadband the range of that point is zero to 10 which I can take it here.
我会拿走那个显示器。
I will take that display.
好的。
All right.
这就是逻辑的海洋。
So this is this a sea of logic.
我们去缅因州吧
Let's go to Maine.
这是博客。
This is the blog.
现在我在这里所做的事情非常重要。
Now what I did here and this is very important.
现在我投票的是我的水平。
Now Id vote for is my level.
所以这意味着重命名时间。
So that means is rename the time.
这对我来说很容易理解。
This would be easy for me to understand.
这就是我的观点，我认为这是不好的部分。
And this is my point is I think this is the bad part.
好的。
OK.
这次是按绿色按钮。
And this time by the green button.
好的。
OK.
所以我想说压力小于 35。
So I'd say on the level less stress that less than 35.
好的，等一下。
OK wait a second.
重命名为.
Rename this is.
好的。
OK.
并且液位低于出口点。
And the level is less than the exit point.
然后我用 100% 的价值来填补这个空白。
Then I'm filling the void with 100 percent value.
100% 驱动墙。
Actuating the wall at 100 percent.
好的。
OK.
那么一刻。
So moment.
好的。
All right.
因此，当液位达到此水平时，应开启新的设定点填充。
So when the level is this then new set point filling should be on.
我们就在这里看看。
Let's see right here.
我不需要读东西。
I don't need to read stuff.
好的。
All right.
所以它保存在反馈值和值滑移中。
So it saves in the feedback value and the value slips.
您此时看到的新设定点，特别是您需要填充的点。
The new set point you see at this point particularly this point you need filling to be on.
好的。
OK.
所以你可以看到这里已经填充了。
So you can see that filling is on here.
因此，当您这样说时，即使水平低于您的设定点也是正确的。
So when you say so even right when the level is less than you set point.
所以这就是它所说的。
So that's that's what it says.
并且水平低于新的设定点，填充应该在履行时获得值 10.0，这意味着填充现在正在连续进行，并且当您将它们移动到十点或两点感觉时结合使用此移动。
And the level is less than new set point filling should be on fulfilling will get the value 10.0 which means filling is on continuously now and using this move combined when you move them out to ten point or two feeling.
现在，如果情况是错误的，那么选票仍然有效。
Now if the situation is false this will still have the ballot in point.
哦，这就是为什么我使用这个逻辑。
Oh that's why I'm using that logic.
好的。
OK.
现在，当该值是一个级别时，它会超过设定点。
Now when the value is a level it's more than setpoint point.
现在这不是一个新的集合。
Now this is not a new set.
这比诺玛斯更重要。
This is more than Normas at point.
回到这里，所以价值比这里更多。
Coming back here so value is more than it is here.
就在此时。
Exactly at this point.
好的。
OK.
此时你可以说此时此刻，因为这是增值，并且价值超过了那个点。
At this point you can say at this point because this is increasing value and the value is more than that point.
那么此时你已经完成了所有这些。
Then you have filling all this off at this point.
这一点就到此为止了。
This point here this is off.
所以我觉得你不应该填写这个。
So I move the feeling well you don't owe to filling this off.
现在每个人都在这里做什么。
Now what everybody is doing here.
按下排水按钮进行排水，这一辆与上一辆相同。
Drained by the drain button is pressed the train by the end is the same as the last one this one.
好吧，我们最终成功了。
Well we made it in the end.
但是按照这种逻辑，当您进入此过程时，如果按下此按钮，则会变形为约会世界，这意味着扭伤正在发生，如果未按下此按钮，则将训练移至零，这意味着训练已关闭。
But in that logic when you go into this if this button is pressed morph into the dating world which means spraining is on if this button is not pressed move zero the training which means training is off.
因此，我们需要编写为返回时条件相同的游戏。
So we need to write as the conditions were restis same in play to go back.
好的。
OK.
让我们将该逻辑下载到 PC 中看看结果。
So let's see the results by downloading this logic into the PC.
但我确实指出一切看起来都很好。
But I did point everything looks OK.
好的。
All right.
尝试将其最小化一点。
Try to minimize it a bit.
我的意思是你可能会。
I mean you might.
我的意思是把窗户分开。
I mean split the windows.
好的。
OK.
现在我刚刚注意到这是一个新的设定点，这是我的设定点，我只会增加设定点，但这是失败的。
Now now I just just noticed here is this new set point and this is my set point I would just increase the set point this is failing.
现在我确实平衡了零成功的工作，就像最后一个例子一样失控。
Right now I did balance zero successful work as an out of control like the last example.
所以没有那么高。
So it was not as high as.
这就是错误。
That's the error.
正如之前我们所看到的，错误始终存在。
So as previously we have seen the error is always there.
如果我再次变绿，感觉将低于 2.4，并且还会增加。
If I go green again the feeling will be on below 2.4 and this is going to increase.
所以你会注意到，到目前为止，如果需求为零，这种感觉就会持续下去。
So you will notice that as of now if the demand is zero the feeling gets on.
力矩值低于设定点。
The moment value goes below the set point.
让我们在这里再看一下。
Let's look at that again here.
感觉是时间因为滞后。
The feeling is time because of the lag.
所以现在正在发生这种情况。
So this is happening now.
任何人都是死区 所以边点是 2.4。
That's anybody who's a deadband So the side point is 2.4.
我将把我的债务增加到 1.0。
I'm going to increase the debt mine to 1.0.
好的。
OK.
所以在这里我们几乎赢了。
So here we we almost won.
所以现在你可以看到新的设定点实际上是 1.4，因为你点 1.4 是因为 2.4 减一是 1.4 情况，即你所说的点。
So now you can see the new set point is actually 1.4 because you point 1.4 is because 2.4 minus one is 1.4 case that is and you said point.
这是一个新的填充设定点。
This is a new set point for filling.
现在我要沥干液体。
Now I will drain the liquid.
所以您会注意到该值小于该点。
So you will notice the value is less than that point.
但填充未开启，因为填充现在处于新的设定点。
But filling is not on because the filling is on the new setpoint now.
所以我可以排出液体中的值，你会看到没有控制动作。
So I can drain the value in the liquid and you see there is no control actions.
由于这一点，没有任何感觉发生。
There is no feeling happening because of that point.
现在我将返回并排出更多，因此当它低于 1.4（这是一个设定点）时，填充将恰好在此处进行，并且将再次达到 2.4，这将始终尝试达到 2.4，但它永远不会因为它是一种类型。
Now I will go back and drain it more so when it goes below 1.4 which is a set point then the filling would be on exactly here and it would be on and again reaches to 2.4 which will always try to reach 2.4 but it can never because it's on a type.
因此，如果我再次排水，我可以使用死区，并且此处的填充将只有 1 3 4 或低于 1。
So again if I drain I can use a deadband and the filling will be on only had 1 3 4 or below 1 for here.
好的。
Okay.
因此，如果我们绘制它正在运行或现在保存项目，您将看到它正在填充雨的曲线的响应，并且您可以看到由于死区的存在，与上一个相比已经使用了振荡频率。
So if we draw it's going or now save the project you will see the response the curve it's filling rain and you can see the oscillation frequency has been used compared to the last one because of the presence of deadband.
因此，如果使用了该振荡频率，您可以看到填充壁的切换响应已被使用，现在重新填充将具有更长的寿命。
So if this oscillation frequency has been used you can see that the switching response of the filling wall has been used and now refilling will have more life.
这张图解释了我希望这是有道理的。
And this graph explains that I hope this is this makes sense.
就是这样。
And that's how.
通过在系统中加入死区，您实际上可以减少严重的撕裂，并且您的过程将持续更长时间，因为您的执行器可以在更长的时间内完美工作。
By including a deadband in your system you can actually have less severe and tear and your process will be you know this will last longer because your actuators are perfectly working fine for a longer time.
好的。
OK.
我希望这个教训有意义。
I hope this lesson makes sense.
在接下来的下一次聆听中，它将从控制开始。
And in the next next listen it will start with the control.
好的。
All right.
感谢您的观看。
Thank you for watching.
