【Abstract】 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.更多还原
