For the uncompensated system found in problem 3.(a) Design a PD compensator,Gc(s) =KP+KDs, so thats=−4±j4 are the dominantroots of the close-loop system characteristic equation. As part of the design, determinethe compensator gainsKPandKD. (Do not use Matlab for this part.)(b) Plot the step responses of the uncompensated and PD compensated system. (Hint: usestepandhold onfunctions)(c
