Abstract

Solid rocket drive system based on switched reluctance motor is established through the working principle of switched reluctance motor, and the closed-loop precise control of solid rocket drive system digitization is realized by the control method of pulse width modulation technology. The gravity value of solid rocket drive system is measured by the vertical deviation measurement method based on attitude error observation. The attitude datum of solid rocket drive system is ob-tained by the relationship between the vertical deviation and the attitude error of solid rocket drive system. The state space of solid rocket drive system is estab-lished by the attitude datum obtained. The horizontal gravity component estima-tion model of the real gravity value of the solid rocket drive system is established by the state space model, and the accurate gravity value of the solid rocket drive system is obtained by the estimation model. The simulation results show that the method can effectively measure the gravity value of solid rocket driving system, and the errors of measuring the gravity of solid rocket driving system are less than 1%. © 2021.
