A process has the following block diagram representation

(a) Will the process exhibit overshoot for a step change in u? Explain/demonstrate why r why not.

(b) What will be the approximate maximum value of y for K = K₁K₂ = 1 and a step change, U(s) = 3/s?

(c) Approximately when will the maximum value occur??

(d) Using Simutink, plot both the actual fourth- order response and a second-order-plus-time- delay response that approximates the critically damped element for values of ?₁ = 0.1, 1, and 5. What can you conclude about the quality of the approximation when ?₁ is much smaller than the underdamped element?s time scale? about the order of the underdamped system?s time scale?
