Abstract:

In view of the attitude control problem of a hypersonic vehicle with range of random parameter perturbations a predictive sliding mode control method based on trajectory linearization and extended Kalman filter (EKF) is proposed. Using trajectory linearization method, a linear time-varying error adjustment model is established from the nonlinear model of hypersonic vehicle. The statistical information in the linearized model caused by parameter perturbations is expressed in the form of parameter covariance matrix by analysis of the statistical characteristics of parameter errors, then the EKF is designed to filter the disturbed error state. Finally, the predictive sliding mode control method is used to design the error stabilization regulator to realize the rapid stabilization of the system. The proposed method is robust to both nonlinear disturbances and random parameter perturbations. Simulation results verify the effectiveness of the proposed method.
