Briefly explain.
1) Clearly write out your analysis. 2) Provide simulation results to validate your design. Problem: Use the subsequent block diagram to answer the following questions, where $G_p(s) = \frac{s + \alpha}{s(s + \beta)}$, $G_c(s) = K$, and $H(s) = 1$, where the gain is defined as $K \in \mathbb{R}^+$. R(s) + E(s) U(s) C(s) Gc(s) Gp(s) • H(s) Design a Controller by finding the values of K, $\alpha$ and $\beta$ such that the % Overshoot = 4.32% and the Time to Peak ($t_p$) is 3.14 [sec.]. This controller also needs to set the Steady State Error for a Unity Ramp Input as equal to 1/10.
