基于小增益定理的MIMO非线性系统的自适应控制

摘要

A novel direct robust adaptive fuzzy control is proposed for a class of nonlinear composite systems with similarity in this paper. The design is based on input-to-state stability(ISS) approach, small gain theorem, and the T-S logic systems is used to approximate the uncertain system function. It proves the closed-loop system is semi-globally uniformly bounded .%针对一类具有不确定函数控制增益的非线性相似组合大系统，提出一种直接鲁棒自适应控制设计器．基于输入到状态稳定性质和小增益定理，并利用T-S模糊逻辑系统逼近不确定函数，设计直接鲁棒自适应控制器．通过理论分析证明闭环系统半全局一致终结有界．
