基于小增益定理的MIMO非线性系统的自适应控制

Adaptive Control for a Class of MIMO Nonlinear Systems Based on Small Gain Theorem

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.

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 .
