Suppose that the closed-loop transfer function He(s)control system is given by:= Y(s)/R(s) of a 2nd-order feedback H_{c l}(s)=\frac{K_{1}}{s^{2}+\left(2+K_{1} K_{2}\right) s+K_{1}} (a) Compute the values of the constants K₁ and K₂ that will produce a unit step responsewith maximum overshoot Mp = 0.046 and 2% settling time ts = 1.43 s. (b) Define He(s) in MATLAB and use the function step info ( ) to list the step response characteristics of the system. Submit your code and its output. (c) Plot the unit step response of the closed-loop system in MATLAB using the function step () and display Mp and ts on the plot. Submit your code and plot.
