A Simple Feedback Control Example 

@CognitiveNetwork The input to the system is X. The gain K is a parameter of the controller that we set to get the desired system behavior. The gain affects what the system will do to X to get the output Y.

@CognitiveNetwork The subtractor computes the error between the output Y and the desired value X (the input to the system is the desired value). The error is used by the controller (the GC(s) box) to adjust the input to the plant (the P(s) box) to make the output what we want it to be.

wow thanks, ive been looking for a while to find a channel like yours. Cheers

@CognitiveNetwork The gain could be implemented using an operational amplifier. It depends on how you implement your system.

Never think abaut this before

@impodds I believe the video is correct. When you multiply through by s+1, you end up with a 1*(s+1) and a k term, which give you s+1+k.

Hi professor, you forget to put the link of this video on the course's webpage.

Can you do a similar one for a Feedforward System ?

helpful staff..thanx

why do you use the notation c for the controller and s for the transfer function? and what do they stand for?

play at 1.5 speed

aren't you suppose to have s^2 + 2 + k, in the denominator?

Thank u..it help me a lot

thanks .. very helpful

saved my bacon I think!

thank you!

lol me2, I was like nope not gonna multiply by the reversed A/B if you know what i mean
