Use Simulink to plot the effects of nonlinearities upon the closed-loop step response of the antenna azimuth position control system shown on the front endpapers, Configuration 1. In particular, consider individually each of the following nonlinearities: saturation (±5 volts), backlash (dead band width 0.15), dead zone (-2 to +2), as well as the linear response. Assume the preamplifier gain is 100 and the step input is 2 radians.
