摘要： 针对一类不确定非线性多变量系统，应用带有监督控制功能的间接型自适应模糊控制方法，在不要求被控系统增益矩阵可逆的条件下设计了自适应控制器.这种自适应控制器不仅能够保证闭环系统的所有信号有界，而且使跟踪误差收敛到原点的一个小领域内.仿真结果表明了该方法的有效性.

Abstract: By using the indirect adaptive fuzzy control approach with supervisory control performance, the adaptive controllers are proposed for a class of uncertain MIMO nonlinear systems under the mathematic conditions where the gain matrices need not be nonsingular. The proposed adaptive controllers can ensure not only the all signals of closed-loop systems are bounded but also the tracking error converges to a small neighborhood of the origin. The simulation results verify the effectiveness of the approach.
