A control method of the Deployable Thrust Pointing Mechanism(DTPM) used for electric propulsion satellite is designed, which is successfully applied to a new generation of all-electric propulsion communication satellite platform for the first time. Through the design of a highly integrated drive and control hardware platform, the rapid iteration of inverse kinematics with preset initial values, the shortest path planning strategy based on local optimization of safe path points and the adaptive multi-axis synchronous control method, the contradiction between high-precision pointing, high-safety motion of the DTPM and the limited computing resources on satellite is solved. The verification results show that the DTPM is safe and reliable in the process of orbital transfer, momentum wheel unloading and other tasks, without collision with the surrounding environment and itself, and the pointing accuracy is better than 0.1°, which meets the needs of satellite electric propulsion applications.
