一种多输入-多输出模糊自适应控制方法的研究

THE STUDY FOR A KIND OF MULTI INPUT MULTI OUTPUT FUZZY ADAPTIVE CONTROL APPROACH

针对多输入-多输出(MIMO)非线性系统基于模糊基函数向量提出了一种新的自适应控制方法.在该方法中,首先将非线性系统线性化,然后利用模糊基函数向量自适应学习系统不确定向量的上界,模糊基函数向量可作为补偿控制器的一个参数.

In this paper, a novel adaptive control approach based on fuzzy basis function vector is presented for Multi input and Multi output(MIMO) nonlinear systems. The nonlinear plant is first linearised, the fuzzy basis function vector is then introduced to adaptively learn the upper bound of the system uncertainty vector, and its output is used as the parameters of the compansator in the sense that both the robustness and the asymptotic error convergence can be obtained for the closed loop nonlinear control system.
