00:01
So we can put these things into two, right.
00:04
We can have openloop up here.
00:09
This is openloop system.
00:13
And if you want to perhaps draw it yourself too.
00:18
It's just very simple.
00:20
Consists of very simple components.
00:24
This could be it.
00:28
Where we have input here and we'll have output the other side, right.
00:38
We'll have a controller here and then you'll have a control process here, all right.
00:51
So this is just about openloop system.
00:54
But then if you look at the closed loop system.
01:04
It's different because you have a number of things that are related or connected.
01:12
So you'll have that comparator that is linked to a control action center.
01:20
Then to the output.
01:22
But in here we have, in between here we have another intermediary.
01:30
That controls these other ends, all right.
01:35
So we like to call those comparator, all right.
01:45
This is a control action.
01:52
Then you'll have the measuring element.
01:54
Okay, let's call this feedback measuring center.
01:59
This is the error signal transfer there.
02:05
We'll have output the other side and we'll have input these other.
02:12
So if you want to differentiate between these systems is very simple.
02:16
You just have to say that openloop system is a system in which the input of the controlling actions do not depend on the output, all right.
02:27
But then the closed loop systems, you know, the input or let me say controlling action will depend on the output, okay.
02:38
We call this feedback system.
02:41
But then for the other one we call it a times non -feedback system.
02:54
Okay, and there are only two components in the openloop system.
03:00
We have just the controller and the controlled process...
