Abstract

According to the tracking error of reaction control system (RCS), a new precision control strategy is proposed for the initial reentry phase of reentry vehicle. Firstly, a nonlinear disturbance observer (DOB) is used for observing the model uncertainty and/or external disturbances. Secondly, a sliding mode control system for the fast loop and slow loop is designed by back-stepping style, and obtained the optimal combination of RCS by linear optimization. Besides, a Integral PWPF Modulator (IPWPF) is proposed based on traditional PWPF modulator, and its stability is proved by a describing function. Finally, the simulation indicates a great precision of the method.
