Question
The closed-loop transfer function of a 2nd-order feedback control system is: H_{c l}(s)=\frac{Y(s)}{R(s)}=\frac{K}{s^{2}+2 s+K} (a) Find the range of the constant K for which the unit step response has Mp ≤ 0.163. (b) Find the range of the constant K for which the unit step response has tr≤ 0.9 s. (c) For what value o
