Abstract: |
Based on dynamic surface control and the nonlinear disturbance observer technique, it proposes a nonlinear adaptive backstepping global sliding mode control system for a typical cyber physical system(CPS) with aerodynamic coefficients and external disturbance uncertainties. The dynamic surface control technique can provide the capability which can solve the problem of “explosion of complexity” in backstepping sliding mode controllers. The nonlinear disturbance observers are employed to observe the arbitrary model uncertainties of nonlinear flight dynamic system. The global sliding mode control method is used to improve the response rate and the precision of the tracking. The simulation results show the effectiveness of the proposed control system. |
