【摘要】 针对一类不确定非线性多变量系统,提出了一种带有监督控制功能的直接型自适应模糊控制方法。本方法设计的直接型控制律由两部分组成:直接型模糊控制项和监督控制项。与已有的关于非线性MIMO系统的自适应模糊控制方法相比较,该方法具有监督控制功能,扩展了现有的自适应模糊控制理论。基于Lyapunov稳定性理论,提出的方法能保证闭环系统的所有信号是有界的以及跟踪误差收敛到小的零邻域内。仿真结果表明了该方法是有效的。更多还原

【Abstract】 A direct adaptive fuzzy control approach with supervisory control performance for a class of uncertain MIMO nonlinear systems is proposed.In this novel method,the proposed controllers consist of two parts:the direct fuzzy control term and the supervisory control term.Compared with the existing research results with respect to the adaptive fuzzy control of uncertain MIMO nonlinear systems,this novel method has the supervisory control performance,and then the adaptive fuzzy control theory is further developed.Based on the stability Lyapunov theory,it can be ensured that all signals in the closed-loop system are bounded,and the tracking errors converge to a small neighborhood around zero. Simulation results indicate the effectiveness of the proposed approach.更多还原
