Abstract

This paper establishes a precise model of near space interceptor with RCS and presents a robust adaptive attitude control law for it. Based on the normal model of the interceptor, this paper focuses on the analysis of all kinds of disturbance that may exist in the model, such as centroid drift and thrust misalignment, and gives the precise model of the disturbance. Then, the robust adaptive attitude control law is designed by using the back-stepping method and Nonlinear Extended State Observer(NESO). Back-stepping method is used to guarantee the system's stability and robustness, and NESO is used to estimate the integrated disturbance. The PWPF modulator is used to discretize the continuous control law. Finally, numerical simulations are performed using longitudinal attitude channel and the simulation results demonstrate the effectiveness of the attitude control law.
