Abstract

Abstract: A stochastic control scheme of adaptive robust trajectory tracking is proposed for near space vehicle (NSV) with stochastic noise input disturbances, Poisson random fluctuation disturbances, and control input saturation. The effective tracking of the height and speed reference signals is realized. For the outer loop trajectory control, the robust stochastic controller is designed for the height subsystem and the speed subsystem respectively. Additionally, the required attitude angle reference signals for the inner loop attitude control are obtained by converting the equivalent control input via numerical calculation. For the inner loop attitude control problems, an adaptive robust stochastic control scheme based on an auxiliary system is designed according to the backstepping control (BC) method, dynamic surface control (DSC) technology, and stochastic robust control method. As a result, precise attitude tracking of NSV under stochastic disturbances is realized, and the influence of multiple stochastic noise disturbances and parameter uncertainty is weakened. The satisfactory robust H∞ tracking control performance of NSV is obtained, and numerical simulations further verify the effectiveness of the proposed scheme.
