Consider the system shown below. Design a lag-lead compensator such that the static velocity error constant Kv is 20 sec^-1, phase margin is 60°, and gain margin is not less than 8 dB. (5%)
Submit your paperwork (analysis and design procedures, Matlab program, and the following plots including:
- Bode plot of plant G(s)
- Bode plot of Gc(s)
- Bode plot of Gc(s)G(s)
- Nyquist plot of G(s)
- Nyquist plot of Gc(s)G(s)
- Bode plot of closed-loop transfer function and indicate the value of bandwidth.
- Calculate the closed-loop poles
- Plot the unit-step and unit-ramp response curves of the compensated system.
Gc(s) = s(s + 1)(s + 5)
