PID控制与模糊PID控制在电机调速系统中的比较与仿真

PID Control with Fuzzy PID Control Based on MATLAB in Motor Speed Control System

对电机调速系统中两种控制即常规PID控制、模糊PID控制进行了分析比较,用MATLAB语言结合具体实例进行仿真,最后给出了仿真实验结果。结果显示常规PID控制精度和鲁棒性降低,而将PID控制与Fuzzy命令的简便性、灵活性以及鲁棒性融为一体的自适应模糊PID控制器则显示出具有方法简单、快速、控制性能高准确的特点。

In this paper,two control motor speed control system,i. e. conventional PID control and fuzzy PID control,are analyzed and listed with results of specific examples by MATLAB language simulation. The final results showed that the conventional PID control accuracy and robustness decreased,while adaptive PID control system with a simplicity,flexibility and robustness process with fuzzy commands. Therefore,the adaptive PID controller has a simple,rapid,controlled performance characteristic than that of the conventional PID control.
