In this paper, the friction generated in gas-flow regulation of ducted rockets is considered, and a compensation method is discussed to eliminate its effect. First, the dynamic mathematic model of gas flow–regulating system considering friction is established and analyzed. Then, the mechanism of friction-compensation method based on additional dither signal is proposed, and the compensation loop with adaptive-amplitude dither signal is added to the original system to overcome the effect of the varied friction. The simulation results show the validation of the adaptive dither signal in solving the problems caused by the variable friction in gas-regulation system of ducted rockets.
