摘　　要：为改善压铸机在生产现场的抗干扰性,提高系统的稳定性,采用自适应模糊PID控制技术,进行了模糊算法设计及压射系统数学模型的分析。利用模糊控制器的智能非线性特征弥补PID控制器不足,更好地控制电液比例阀,使系统达到更优的控制状态。通过实验仿真可知,该算法可以减少系统的稳态误差,提高系统抗干扰性。In order to improve the anti-jamming and the system stability of the die-casting machine at the production site, the fuzzy algorithm was set and the mathematical model of the press-shoot system was analyzed by using adaptive fuzzy PID control technology. The fuzzy controller was used to make up the PID controller, which can better control the electro-hydraulic proportional valve, and makes the system get a better control state. The experimental results show that the algorithm can reduce the system error and improve the anti-jamming performance.
