摘　　要：根据拖拉机液压悬挂系统的特点,提出电控液压悬挂系统模糊控制器的设计方法,建立了模糊推理系统。利用Matlab对悬挂系统耕深分别进行了模糊控制和PID控制仿真,研究结果表明,模糊控制策略控制比PID控制更能适用于拖拉机液压悬挂系统。Based on the character of the electronic hydraulic hitch, this paper chose the right control method. Besides it also introduced the design method of electronic hydraulic hitch system fuzzy controller, built Fuzzy Inference System（FIS）. The simulation model of hitch fuzzy control system and PID control system was built with MATLAB, and the simulation analysis indicated that fuzzy control method is more satisfied the request of system performance than PID control method.
