摘要
针对传统直流调速不能有效克服非线性因素,难以满足某些特定场合对高精度、高性能的控制要求,提出了基于模糊PID控制的直流电机调速系统。介绍了模糊控制器的原理及特点,分析了模糊PID控制器的控制原理,并确定了模糊语言变量和隶属函数,制定了模糊规则和反模糊化方法,最后利用Matlab/Simulink对直流电机调速系统进行建模仿真。仿真结果表明:直流电机调速采用模糊PID控制比传统PID控制具有更好的控制精度、鲁棒性,并提高了电机动、静态性能。
The traditional DC speed regulation can not overcome nonlinear factors and is hard to meet certain occa- sions control requirements of high precision and high performance puts forward, the DC motor speed control system based on fuzzy PID control. Introdues the theory and characteristics of fuzzy control, analyzes the control principle of the fuzzy PID controller, determines variables of fuzzy anguage and sub-ordinative functions, and stipulates the methods of fuzzy rules and inverse fuzzy. Finally, the modeling and simulation are made with Matlab/Simulink, the result shows that the DC motor speed control applying fuzzy PID control has better control precision and robustness than traditional methods, and it also improves dynamic and static performance of electrical motor.
