Consider the PID and I-PD controllers shown below, each connected to a standard first-order system plant Gp(s) = 1/(TS+1): kp kas Gel G(8) Controller k/8 kp G(8) (a) Taking the parameter values as 7 = 0.1, kp = 0.5, ki = 1, ka = 0.1, set up a Simulink diagram for each design, using a Step block for the reference r input, and two Scope blocks to record u and y. Include a sketch or screenshot of both designs. (b) Now run both simulations for the reference step input r(t) = 1+(t), and provide plots for y and u for each case. How does the performance of the two designs compare?
