摘 要：正This paper is considered with the robust stabilization problem of a class of nonlinear systems with bounded uncertain time-invariant parameters.A robust control Lyapunov function（RCLF） is introduced for the considered *** on the RCLF,a globally asymptotically stabilizing controller is then *** proposed controller is robust under the variant of system *** the applications of the proposed scheme,the stabilization of uncertain feedback linearizable systems and the unified chaotic system are investigated,respectively.A numerical example on the unified chaotic system is also provided to illustrate the effectiveness of the presented method.
