模糊自适应PID控制方法研究与仿真

The Method Study and Simulation of Fuzzy Self-adaptive PID Control

对于非线性、时变性的系统来讲,传统PID控制难以达到满意效果。利用模糊推理的方法实现对PID参数的在线自动整定,并且在Matlab软件环境下进行了研究与仿真。仿真结果表明,参数自适应模糊PID控制能使系统控制响应快、控制稳定,且具备了良好的动态性能。

Conventional PID control can not reach a satisfactory result in nonlinear and time varying systems.In this study,a fuzzy inference method is adopted to realize the automatic regulation of PID parameters.The application of the controller in a certain system is also simulated in Matlab.The results of the simulation show that the fuzzy self-adaptive control has certain advantages over conventional ones in the aspects such as fast-response,high-stability and better-flexibility.
