Use MATLAB to find the resonant peak, Mpeak, resonant frequency Wr, and bandwidth B W of the following unity feedback contml systems. Make sure that the systems are stable.

(a) 5 G(s) = s(1 + 0.5s)(1 + 0.1s)

(b) G(s) _ lO(s + 1)
- s(s + 2)(s + 10)

(c) G( ) 0.5 s = s(s2 + s + 1)

{d) G woe-s

(s)= s(s2 +5s+5)
