MATLAB-Based Optimization Design of Parameters in the Fuzzy Control System

该文提出了一种基于MATLAB环境下,利用优化工具箱和模糊逻辑工具箱以及M函数文件,使用单纯形法对模糊控制器中的量化因子和比例因子进行自寻优,可获得一个基于一定性能指标的次优或最优模糊控制器。以二阶系统为例进行了计算机仿真,仿真结果表明该方法具有良好的收敛性,使系统的动态性能得到明显的改善。

A design method is presented for fuzzy control parameters self-optimizing using simplex method based on MATLAB to obtain optimal or sub-optimal fuzzy logic controllers. For the control of industrial processing, a computer simulation with second -order system model is made. The simulation result shows that the proposed algorithm is of good convergence and improves the dynamic characteristics of the control system.
