| 摘 要： | 压铸机工作环境恶劣,干扰较多,使参数发生较大变化,影响系统的稳定性,传统的PID线性控制在被控对象发生变化时,控制特性也随即发生变化。针对这个缺点,采用自适应模糊PID控制技术,并利用模糊控制的智能非线性特点来弥补PID控制器,从而对电液比例阀进行良好的控制,使系统达到一个最优的控制状态。通过实验仿真可知自适应模糊PID控制方法的可行性。

| Abstract: | Die casting machine working in bad environments, with more interferences, making parameters take place great changes, affects the stability of system, in the traditional PID linear control when controlled object changed, the control characteristic changed immediately. According to this shortcoming,this paper using Adaptive fuzzy PID control technology, and by using the nonlinear characteristics of fuzzy control to compensate PID controller, thus to the good control of electrohydraulic proportional valve, making the system to achieve an optimal control state. Through the simulation results we can see that the adaptive fuzzy PID control method is feasible. |
