摘要
介绍直流调速系统工作原理,在分析模糊PID控制器原理的基础上,充分结合传统PD控制响应速度快和模糊PID控制精度高的特点,设计了一种阈值型模糊PID算法,应用于直流电机调速系统。通过在MATLAB/Simulink中与传统PID控制进行仿真分析对比,证明了这种算法的有效性。
The operating principle of the speed governing system of DC Motor is introduced.Based on analyzing the principle of fuzzy PID controller, combining sufficiently the advantage of the high precision of fuzzy PID controller and the fine response of the traditional PD controller,a fuzzy PID controller with the threshold switch is designed.The effectiveness of the arithmetic has been proved Through simulating in MATLAB/Simulink with traditional PID controller.
