摘要:

针对多变量非线性系统的控制问题,提出了一种具有良好控制效果的模糊预测控制方法。首先采用快速聚类法和递推最小二乘法辨识得到非线性系统的T-S模型,然后对系统进行线性化,并基于线性化的模型设计模糊广义预测控制器并对非线性对象进行在线自适应控制。对一个带时延的强耦合二变量非线性对象进行仿真,结果表明对于具有时变性的非线性系统,该方法具有很好的控制效果。

Abstract:

A very good control effect algorithm of fuzzy predictive control based on nonlinear multivariable system is presented. Firstly, the nonlinear system of T-S model is identified by fast clustering and recursive least square method, and the linear model is gotten. Then the fuzzy generalized predictive controller based on linear system is designed to control the nonlinear object adaptively. The simulations for the variable nonlinear object with delay time and strong coupling show that this algorithm has good control effects.
