T R(S) C(3) D(S)Go (3) G(s) Gozan (0) H(s) 10 Consider the system given above with D(s) = G(s) = (5+2) H(s) = 1 and answer (s+2)(s+4) the following questions. 0.572 - z-1 and simulate the unit Consider the digital controller transfer function as D(z) step response of the digital control system in MATLAB/Simulink for the sampling period values T=0.5, T-1, T=2, T-3, 7-4 s. (Keep G(s) continuous in Simulink.) a. Plot the output of the system for those simulations with different sampling periods, together with the continuous output you obtained in Question 1. b. Plot the discrete-time control signal of the system for those simulations with different sampling periods, together with the continuous control signal you obtained in Question 1 c. Find the sampling period value which makes the system marginally stable from the interval you found in Question 4. Simulate the unit step response of the system for this sampling period value and plot it
