R(S) C(s) Gc(s) (s + 0.6) (s +0.58)(s + 0.02) Figure 1 Block diagram of hybrid electric vehicle (HEV) Figure 1 shows the block diagram of the speed control of a hybrid electric vehicle as a unity feedback system where the output, C(s) is the output voltage of the speed sensor.
C. Then, assume that the system specifications require zero steady-state error for step inputs, a steady-state error for ramp inputs 2% a %OS 5 4.32%, and a settling time 52. Show that the specifications cannot be achieved only with a proportional controller. Design a controller to fulfill these specifications. d Obtain the step and ramp responses of the final design in (a), (b) and (c) using MATLAB. Clearly titled and labelled your graphs. Fill in Table 1. Rename the heading of the columns, for example, uncompensated system or gain-adjusted system or PID compensated system etc. e.
