一种基于Matlab的参数自调整模糊控制器的设计方法

本文介绍了一种在MATLAB的模糊控制工具箱中，通过编写S函数实现对量化因子和比例因子的在线自动调整来设计模糊控制器，从而有效地实现参数自调整模糊控制器的设计方法。为了验证参数自调整模糊控制器的优越性，分别进行了空调温度控制系统的PID控制、常规模糊控制和参数自调整模糊控制的仿真研究。结果表明，参数自调整模糊控制器较之常规的模糊控制器，在被控对象特性变化或较大扰动的情况下，控制系统能保持较好的性能，是一种较理想的控制方法，具有广阔的发展前景。

Design of Parameter Self-tuning Fuzzy Controller Based on Matlab

This paper describes how a fuzzy controller is designed with MATLAB fuzzy toolbox and how the parameter self-tuning fuzzy controller is designed based on the on-line automatic adjustment of the S-function and .scale factor. In order to verify the superiority of the proposed self-tuning fuzzy controller, simulations of applying PID controller, fuzzy controller, and self- tuning fuzzy controller in temperature control of air-conditioning system are respectively performed. The result shows that parameter self-tuning control is an ideal method, and can achieve the ideal response curve. It has practical guiding effect and application value in research and engineering applications, and will have broad developing prospects.
