摘要
本文针对非线性大系统,利用模糊系统的逼近能力,提出了一种分散自适应模糊控制器设计的系统方法.控制结构中采用分散模糊系统去自适应补偿过程不确定性,同时用模糊控制器的输出代替常规变结构控制律中的符号函数.利用李亚普诺夫理论,证明了控制算法是全局稳定的,跟踪误差可收敛到零的一个邻域内.
A systematic methodology to the design of a decentralized adaptive fuzzy controller forlarge-scale nonlinear systems is proposed in this paper. The design is based on the approximation capabilityof fuzzy systems. The control architecture employs decentralized fuzzy systems to compensate adaptivelyfor plant uncertainties,and replacing sign function in the conventional variable structure control with thefuzzy controller output. By using the Lyapunov theory,the algorithm is proven to be globally stable,withtracking errors converging to a neighborhood of zero.
