AB - 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 obtained 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 established by the  attitude datum obtained. The horizontal gravity component estimation 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%.
