| 摘 要： | 针对异步电动机调速系统的非线性和结构参数易变等特点,采用矢量变换,将模糊控制和PID控制结合起来,建立了模糊自适应PI调速系统的双闭环模糊控制仿真模型,对异步电动机模型参数进行分析整定。MATLAB仿真结果表明该控制器与常规PID相比较,具有良好的稳态精度和自适应能力,没有超调和振荡,明显改善了系统的动态性能,并且具有较强的鲁棒性,为煤矿安全生产发挥了重要的作用。

| Abstract: | According to disadvantages that traditional PID control is difficult to adjust PID parameter for nonlinear and time-variant mine asynchronous motor speed control system,this paper designs fuzzy self-adaptive PI speed control system with double closed-loop fuzzy controller by combining fuzzy control and PID control.The MATLAB simulation results show that this controller has better stability and self-adaptive property and well improved dynamic performance of system compared with conational controller. |
