| Abstract: | In this paper,the adaptive fuzzy s li ding mode control is applied to the attitude stabilization of flexible satellite ,and the detailed design procedure of the fuzzy sliding mode control system is p resented. The adaptive fuzzy control is utilized to approach the equivalent cont rol of sliding mode control,then the adaptive law is derived. The discontinuous control, which guarantees the stability of control system, is developed. Also in order to attenuate the chattering phenomena, another fuzzy controller is employ ed to smooth the discontinuous control.Simulation results show that precise atti tude control is accomplished based on the proposed method. |
