The Nichols diagram for Gc(jω)G(jω) of a closed loop system is shown in Figure P9.22.The frequency for each point on the graph is given in the following table:
Determine (a) the resonant frequency, (b) the bandwidth, (c) the phase margin, and (d) the gain margin. (e) Estimate the overshoot and settling time (with a 2% criterion) of the response to a step input.
