摘要: 提出一种不确定T-S模型的模糊滑模自适应控制方法。通过变换将该模型转换成3个组成部分:线性标称系统,已知非线性部分和未知不确定部分。针对它们设计3个控制器,其作用分别为:强迫系统沿着滑模面运动,消除已知扰动对线性标称系统的影响,克服不确定扰动(采用模糊滑模自适应控制,无需知道不确定的界限)。该方法无需求正定矩阵就能保证系统全局稳定。

Abstract: Fuzzy sliding mode adaptive control method is proposed for uncertain T-S model, which can be translated into the three parts including linear nominal system, known nonlinear part, uncertain part. Three controllers can be designed for the three parts. They are exploited respectively to force system to move along sliding mode surface, to eliminate known disturbance to linear nominal system, to overcome uncertain disturbance(using fuzzy sliding mode adaptive control without known uncertain bound). The method can guarantee global stability without searching a common positive definite matrix.
