Tracking Control Algorithm Based on Photoelectric Sensors for Smart Car System

摘要

In this paper, target identification and trajectory technology are analyzed. The tracking control algorithm based on the photoelectric sensors is proposed. The algorithm utilizes the errors of the location and the signal of route as input parameters, to regulate the output angle of the steering gear. The smart car system includes the straight trajectory control algorithm, the curvy trajectory control algorithm and the S-type trajectory control algorithm according to the different characteristic of the trajectories. The experiment shows that, by using the proposed algorithm, the smart car can move smoothly along the straight trajectory, the curvy trajectory and the S-type trajectory with satisfied accuracy.
