摘　　要：提出一种非线性模糊直接和间接自适应控制的统一设计方法 ,该方法把文献 [1,2 ]中的监督控制器用 D—控制来取代 ,在闭环系统的渐近稳定性分析中取消了要求逼近误差平方可积的条件 ,模糊控制器能克服外界干扰对系统误差的影响。Fuzzy indirect and direct adaptive control algorithms are developed for nonlinear systems. These algorithms substitute “D-controller” for supervisory controller, relax the squared integrity condition of approximation error in references[1,2],which guarantees the stability of the closed loop system. It is proved that these algorithms not only have the stability, but also have the robustness for external disturbances. The simulation results confirm the accuracy of them.
