针对一类状态不可测的MIMO不确定非线性大系统,提出一种基于H_∞跟踪的分散自适应输出反馈模糊控制器.主要工作有:1)通过对观测误差向量进行滤波来确保严格正实条件成立,使得提出的反馈与自适应机制可以执行;2)利用模糊系统提出一种适用于一般非线性大系统基于H_∞跟踪的分散自适应模糊控制方案;3)在统一的框架下处理了控制器奇异性.闭环大系统被证明是稳定的,且输出误差具有H_∞跟踪性能.仿真结果验证了控制器设计的有效性.
For a class of MIMO uncertain uncertain large-scale systems with uncertain state, a decentralized adaptive output feedback fuzzy controller based on H_∞ tracking is proposed. The main work of the dissertation is as follows: 1) By strictly observing the error vector, The conditions are satisfied, and the proposed feedback and self-adaptive mechanism can be implemented; 2) A fuzzy adaptive fuzzy control scheme based on H_∞ tracking is proposed for general large-scale nonlinear systems; 3) Controller singularity. The closed-loop large-scale system is proved to be stable and the output error has H_∞ tracking performance. The simulation results verify the effectiveness of controller design.
