Abstract
In order to improve the automation level of wrecker, fuzzy PID controller for the uprighting was proposed. First, the uprighting model was built in this article. Then, the hydraulic circuit of wrecker uprighting system was built in AMESim. Furthermore, the fuzzy PID controller and the conventional PID controller were simulated respectively in Matlab\Simulink software based on this model. Simulation results show that the fuzzy PID controller has faster step response speed and smaller overshoot than that of the conventional PID controller. The uprighting can be accomplished automatically and smoothly by virtue of the fuzzy PID controller.
