Based on the observer-based method,the convex combination method is used to deal with the uncertain nonlinear function.The fuzzy logic system[1-3]is introduced to deal with the unknown nonlinear function,so that the observation result is closer to the real value,Reduce the observation error of nonlinear system.Based on the Lyapun stability theory,it is proved that the control rate involved can ensure that all signals of the whole closedloop system are semi-global and bounded,and the system state is converged to a sufficiently small neighborhood of the origin.The simulation results show that the proposed method is effective.
