Abstract
For the problem of actuator limitation in the control of aspirating hypersonic vehicle (AHV), this paper proposes a control strategy combined fuzzy approximation system with adaptive control. Firstly, the system is divided into velocity subsystem and altitude subsystem. Then, a new control law is designed. Finally, the uncertainty of the system is estimated based on the universal approximation theory of fuzzy system. This control strategy can both allow the control system with better robustness, and a good restraining effect for the uncertain disturbance. As shown from the simulation results, the method proposed in this paper has more stable than the traditional method in different situations and verifies the effectiveness of the control strategy.
