摘　　要：针对传统PID控制方法难以满足低压铸造控制系统控制精度的问题,文中根据铸造控制过程中的不确定性、非线性等性能特性,研究了Fuzzy-PID复合控制方法。利用Matlab软件中的Simulink工具箱建立控制系统仿真模型,对控制系统进行仿真并比较模糊控制、PID控制和复合控制的仿真曲线。仿真结果表明,Fuzzy-PID复合控制方法完全可行,并且取得了较好的控制效果。The Fuzzy-PID compound control method is studied according to uncertainty and nonlinearity of the casting control process, aiming at the problem that the traditional PID control method is difficult to meet the control accuracy of low pressure casting control system. The simulation model of control system is established by using the Simulink toolbox in Matlab software, the control system is simulated and the simulation curves of fuzzy control, PID control and compound control are compared. The simulation result shows that the Fuzzy-PID compound control method is completely feasible and good control effect is achieved.
