Research on Agricultural Machinery Hydraulic Steering Control System Based on Fuzzy PID Variable Damping Algorithm

The development trend of modern agriculture requires agricultural machinery operations to have stable dynamic performance and faster response speed. Therefore, combining fuzzy control on the basis of traditional PID control, a fuzzy PID variable damping control method is proposed. First, the steering of agricultural machinery The system establishes a second-order model, and then combines this control method to design a fuzzy PID variable damping controller, and changes the system damping ratio by changing the feedback channel gain. Finally, the performance of the control system is compared between the MATLAB simulation and the traditional PID control. The results show that this method can effectively shorten the system response time, reduce the overshoot, and improve the speed and stability of the agricultural machinery steering control.
