Please solve this problem I do not understand If my answer is true, solve it clearly please as my question is clear and plot whatever is needs.
I need a comparison between an Open Loop, Feedforward and Feedback control systems. If you can also use a table with numerical values to compare them in addition to theoretical would be appreciated. Thanks in advance!
