AB  - This article develops a novel sliding-mode surface (SMS)-based approximate 
      optimal control scheme for a large class of nonlinear systems affected by unknown 
      mismatched perturbations. The observer-based perturbation estimation procedure is 
      employed to establish the online updated value function. The solution to the 
      Hamilton-Jacobi-Bellman equation is approximated by an SMS-based critic neural 
      network whose weights error dynamics is designed to be asymptotically stable by 
      nested update laws. The sliding-mode control strategy is combined with the 
      approximate optimal control design procedure to obtain a faster control action. 
      The stability is proved based on the Lyapunov's direct method. The simulation 
      results show the effectiveness of the developed control scheme.
