摘　　要：针对目前特种陶瓷液压机系统参数整定困难的现象,使其抗干扰能力良好,提出一种将模糊控制和常规PID控制相结合的控制方式,将其应用于特种陶瓷液压机控制系统中,通过Simulink建模仿真,对其进行不同信号的激励。通过模糊控制与常规PID控制器仿真结果进行比较,结果表明:当条件变化时,模糊PID能实现参数自整定,得到较好的控制效果,并且能够很好地降低控制对象不确定对系统的影响,一定程度上可以提高系统的跟随性能。In order to solve the difficulty of parameter tuning of special ceramics hydraulic system, and have a good anti-jamming capability and reach a steady state quickly, a control way of combining fuzzy control and conventional PID is proposed, which is used in special ceramic hydraulic control system. The fuzzy PID control- ler is designed and the system simulation model is established by using Simulink software to provide the differ- ent types of incentive signal for the system. By comparing with the conventional PID controller, the result shows that when conditions change, the fuzzy PID parameter self-tuning can be achieved, and could obtain better control effect, which can reduce uncertain impact on the system, the follow performance of the system can be im- proved to some extent.
