基于MATLAB 的模糊PID参数自整定控制器设计与研究

摘要

Design a parameter self-tuning PID-controller based on fuzzy control,which can adjust PID-parameters ac-cording to error and change-in-error.A simulation study of the system shows that the controller both includes the precise character of PID controller and the flexible advantage of fuzzy controller.It can eliminate the steady error of the system promptly.%针对多数工业过程存在非线性、参数时变和模型不确定等问题，设计了一种基于模糊控制的自整定PID控制器。它能根据偏差和偏差变化的需要实时自动调整和优化PID参数。仿真结果表明，该模糊PID控制器具有控制精度高、快速性好和适应性强等优点，可以迅速消除系统误差，保证被控对象具有良好的静态和动态性能。
