Tractor Remote Control Steering System Based on Fuzzy PID Control
In view of the harsh working environment of tractor,in order to ensure the safety of drivers,this paper puted forward a design scheme of remote control steering system for tractor.This paper first analyzed the existing hydraulic steering system of tractor,and on this basis,the structural design and control strategy design of remote steering system were proposed.In the next step,the hydraulic part model and fuzzy PID controller of the remote steering system were built through AMEsim and Simulink,respectively,and joint simulation experiments were carried out.The results showed that the designed remote steering system can realize the steering of tractor.Compared with the conventional PID control-ler,the designed fuzzy PID controller had better control effect,the step response time was shortened from 1.49 s to 1.07 s,the maximum error of sinusoidal tracking response was shortened from 0.028 m to 0.015 m,and the anti-interference was also stronger.
