Question: 4 15 points consider the power flow control system for...

Question details

4. (15 points) Consider the power flow control system for an electric power system, as shown in Figure2 below. Pm is the mechanical power input, while Pe is the electrical power output. Consider k-10, M-2, d-0.5. Consider two controllers: a). Pl controller. Cs)-1+10 b). PID controller: C(s)-1 + 2s+ For each case, compute the poles and zeros of the closed-loop transfer function between Pm(s) and Pe(s). For each case, applying Pm to be a unit step signal, use Matlab to plot the time response of Pe Power system Pa(s Pe(s) C(s) Ms2 + ds +k Figure 2: Power control of an electric power system
