Problem No. 3 Bandwidth (25 points) A unity-feedback control system with: L(s)=-

Problem No. 3 Bandwidth (25 points) A unity-feedback control system with: L(s)=- R(s) + L(s) 15 s(s+s+25) Y(s) Please find (with MATLAB or sketches): (a) Open-loop Bode plots and the gain crossover frequency @gc. (b) Range of frequencies for the closed-loop bandwidth based on your value for @gc. (c) Closed-loop Bode plots and the actual bandwidth frequency. How does it compare with your estimated range in part (b)?
