摘要
利用Simulink仿真软件对该系统的液压补偿机构进行了仿真试验研究,并采用了PID控制、模糊控制和Fuzzy-PI复合控制三种控制算法进行比较。仿真结果表明,Fuzzy-PI复合控制的控制效果均优于常规的PID控制和模糊控制,是一种有效的控制算法;但系统还存在着一定的滞后,还需要改进。
In the paper, the hydraulic compensation mechanism of the system is modeled and simulated by using the Simulink simulation software. And PID control, Fuzzy control and Fuzzy-PI complex control are used and compared with each other in the system. The simulation results show that the control quality of Fuzz- y-PI complex controller is better than regular PID controller and Fuzzy controller. Fuzzy-PI complex control is a kind of effective control method. But there is still something in need of improvement as some time-delay is found in the system.
