Please use a scilab simulation to verify the results and can u also include the code used. Thank you.

A process has the following block diagram representation: (a) Will the process exhibit overshoot for a step change in u? Explain/demonstrate why or 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) Simulate and plot both the actual fourth-order step response and the response for a second-order-plustime delay model that approximates the fourth order system. Using the same second-order-plus-time delay model, what happens when the time constant in the first block is changed to 1 and then 5 ? Compare the step responses graphically.
