The open-loop frequency response of a unity feedback system is given below: @ 1.0 0.15 130° 1.5 R(s) 0.36 1 |G(jw)| - ZG(jw) Sketch the inverse Nyquist plot and determine values of M, and w,. The configuration of feedback system is now changed to include derivative feedback as shown in Fig. P-9.15. Determine graphically the resultant frequency response and therefrom determine values of M, and @₁. Comment upon the effect of derivative feedback on system stability.
