The indirect adaptive fuzzy predictive control of hypersonic vehicle

In this paper, the adaptive fuzzy predictive control is applied to the hypersonic vehicle. The detailed design procedure of the fuzzy predictive control system is presented. The adaptive fuzzy control is utilized to approach the uncertain functions of the hypersonic vehicle and the adaptive law is derived. According to the tracking errors, weighted parameters of the fuzzy system are adjusted on-line to enable the system to approximate the uncertain nonlinear functions effectively. In addition, a robust controller is employed to enhance the performance of the whole system. Simulations results show the proposed control law can restrain the disturbances effectively and have better dynamic and static performances.
