Abstract :
In vehicular radar servo system, parameter variations of the motor and uncertainties have great effects on the position tracking precision. This paper proposes a feedback linearized design method with uncertainties. A robust adaptive controller is designed for vehicular radar servo system. An adaptive compensation scheme is presented to cancel the effect of sensor uncertainties. Adaptive update laws are employed for estimation of the uncertain parameters. A state feedback control law is designed to control the nonlinear radar vehicle servo.
