Question:
A model of an automobile driver attempting to steer a course is shown in Figure P9.18, where K = 6.0.
(a) Find the frequency response and the gain and phase margins when the reaction time T = 0.
(b) Find the phase margin when the reaction time is T = 0.15 s.
(c) Find the reaction time that will cause the system to be borderline stable (P M. . = 0°).
