Design of Motor Speed Regulation System Based on Fuzzy PID Algorithm

为了改善直流调速系统的可控性,使其能够自动调整控制策略,对受控对象的控制尽可能达到最佳性能.将模糊控制算法叠加于直流电机转速、电流双闭环调速系统,进一步确定模糊语言变量以及隶属函数、并制定模糊规则,从而实现模糊控制.另一方面采用Matlab/Simulink对电机调速系统实施仿真和实验分析.从具体的仿真和实验分析结果我们可以得出结论:在性能指标方面,采用模糊PID控制要显著优于常规PID控制,可见模糊PID算法的电机调速系统是具备实用价值的.

In order to improve the controllability of the DC speed regulation system,enable it to automatically adjust the control strategy,and achieve the best performance of the control of the controlled object as far as possible,the fuzzy control algorithm is superimposed on the DC motor speed and current double closed-loop speed regulation system to further determine the fuzzy language variables and membership functions,and formulate fuzzy rules,so as to realize fuzzy control.On the other hand,Matlab/Simulink is used to simulate and analyze the motor speed regulation system.From the specific simulation and experimental analysis results,we can conclude that in terms of performance indicators,the fuzzy PID control is significantly better than the conventional PID control.It can be seen that the motor speed regulation system based on Fuzzy PID algorithm has practical value.
