Abstract:A robust adaptive control method based on main influence elements analysis is proposed for the hypersonic vehicles in strong parameter perturbations case during the cruise phase. Firstly, under the condition of parameter uncertainties, symbolic calculation tools are used to separate the uncertainty terms, and the uncertainty model is obtained. Furthermore, Monte Carlo method is implemented to determine the main influence elements of the uncertainty function vectors, the uncertainty model is simplified. Secondly, on the basis of the sliding mode control, a flight controller is designed combining the parameter adaptive estimation and robust compensation, then the stability of system is proved theoretically. Lastly, a detailed simulation experiment is carried out, which verifies that the flight controller can guarantee system stability and tracking performance even in case of large parameter perturbations. © 2017, Editorial Dept. of JA.
