一类大系统的直接自适应分散模糊控制

ADAPTIVE DIRECT FUZZY DECENTRALIZED CONTROL FOR A LARGE SCALE NONLINEAR SYSTEM

本文针对一类未知非线性大系统，提出了一种直接自适应模糊分散控制策略．设计中，首先在假设各子系统的动态已知的条件下，设计最优分散控制，然后用模糊自适应系统逼近最优分散控制．同时引入模糊滑模控制消除各个子系统之间的相互作用，外部干扰和模糊系统的逼近误差．并对所设计的控制系统进行了稳定性分析．

In this paper, a direct adaptive fuzzy decentralized control is proposed for a large scale unknown nonlinear system. In the design, we employ adaptive fuzzy logic systems to approximate the unknown functions, and introduce error feedback and sliding mode control to deal with the interactions between subsystems, external disturbance and the errors of approximation. Finally, the analysis of the closed loop ia given.
