Electronics and computers arc being used to control automobiles. Figure P9.14 is an example of an automobile control system, the steering control for a research automobile. The control stick is used for steering. 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) Mpo) 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.
