1. Use frequency response methods to find the value of K necessary to achieve a step response with a 10% Overshoot for the unity feedback system shown in Figure 11.1 when a. G (s) = b. G (s) = K s(s+5) (s+10) K(s+2) s(s+4) (s+6) (s+10) K(s+1)(s+5) c. G (s) = s(s+3) (s+6) (s+10) (s+15) You may draw the bode plots by hand or use MATLAB R(S) + G(s) FIGURE P11.1 C(s)
