Abstract

Based on a fuzzy system

a novel nonlinear robust adaptive predictive control method is presented and applied to the re-entry of an aerospace vehicle(ASV). The unknown disturbances and uncertainties are estimated using the fuzzy system in virtue of its approaching ability. A robust adaptive controller is designed using the Lyapunov theory. Because the weight parameters of the fuzzy system are kept unchanged

only two parameters of the robust adaptive controller are adaptively adjusted by tracking errors

so as to simplify the design of the controller. It is shown that the closed-loop system is ultimately bounded on all signals. Finally

the flight control system of an aerospace vehicle under hypersonic conditions is designed by the proposed method. The results show that the response time is about 1.5 seconds and the overshoot is 0

respectively

which indicate the fine robust performance of the proposed method for parameter uncertainty and disturbance.
