基于模糊自整定PID的二质量伺服控制系统的研究

A study of two-mass servo control system based on a fuzzy self-tuning PID controller

在分析了直流伺服系统电学方程和动力学方程的基础上,建立了二质量伺服系统的数学模型及SIMULINK仿真模型。通过MATLAB模糊工具箱和SIMULINK,实现了模糊自整定PID控制器的设计和系统仿真。仿真结果表明用模糊自整定PID控制二质量伺服系统,系统响应快,超调量小,稳定精度高。

This paper presents the making of both math and simulation models for use with a twomass servo system based on an analysis of both electric equation and dynamic equation in a servo system.The design of a fuzzy self-tuning PID controller and the simulation of the whole system are realized by using the MATLAB fuzzy logic tool and SIMULINK. The results of the simulation show that the two-mass servo system with the fuzzy self-tuning PID controller has a fast response, slight overshoot and high accuracy in stability.
