A typical driver has a reaction time of T = 0.2 s.
(a) Using the Nichols chart, determine the magnitude of the gain K that will result in a system with a peak magnitude of the closed-loop frequency response Mput less than or equal to 2 dB.
(b) Estimate the damping ratio of the system based on (1) Mpω and (2) the phase margin. Compare the results and explain the difference, if any.
(c) Determine the closed-loop 3-dB bandwidth of the system.
