摘要

In this paper, a trajectory tracking PID controller is designed for autonomous ground vehicle based on genetic algorithm. Based on the bicycle model, the lateral dynamics model of the vehicle is established, which is further expressed in a transfer function form. Different from previous studies on trajectory tracking control of autonomous ground vehicle, the PID controller parameters are optimized by combining genetic algorithm, in which the tedious and time-consuming problem of controller parameter turning can be avoided. Finally, simulation results show that the designed controller has good tracking performance even in the presence of external disturbance.
