Question4: (CL04) 1. For a plant to be controlled is described by a transfer function G(s), obtain the root locus plot using MATLAB. G(s) = s + 5 e + 7s + 25 2. For the system shown in the Figure, design a Lead compensator such that the dominant closed-loop poles are located at s = -2 ± la Plot the unit-step response curve of the designed system using MATLAB. 7 Ge(s) s(0.5s +1) The compensated system’s closed-loop transfer function is C(s) 7 R(s) s2 + 4s + 7
