Robust Adaptive Compound Control for the High-speed Aircraft with Actuator Dynamics

During the reentry phase of the high-speed aircraft, the atmospheric characteristics are unusually complex, and the density of the atmosphere varies strongly, it is significant for us to design a strong robust adaptive compound controller. Fistly, cinsidering the actual reentry progress, the whole reentry progress is divided into three parts, including the reaction control period, the cmpound control period and the aerodynamics control period; Secondly, the full channel attitude robust adaptive controller is researched based on the nonlinear dynamic inverse theory and nonlinear extended state observer; Thirdly, to achive a better control performance, a smooth distribution coefficient is introduced in allocation system, and the expected control moment is divited into reaction control subsystem and aerodynamic control subsystem; Fourthly, the actuator dynamics were also taken into consideration; Lastly, the numercial simulaion results show that the proposed approach has a excellent ability to solve the compound control problem for the high-speed aircraft.
