Abstract

The invention discloses a satellite control system and an electric propulsion system closed-loop joint test method. A closed-loop joint test is carried out on an electric propulsion system and a control system of a real satellite through a ground test; a time sequence of on-orbit work is comprehensively simulated; and a complete work flow of the control system for debugging electric propulsion toperform on-orbit ignition can be verified, a function of the control system for debugging an electric propulsion ignition flow is tested, a problem that a current satellite ground test cannot effectively verify a combined work function of the satellite control system and the electric propulsion system is solved, the verification flow is complete and sufficient, and economy is good.

Description

technical field [0001] The invention relates to a closed-loop joint test method of a satellite control system and an electric propulsion system, belonging to the field of spacecraft ground testing. Background technique [0002] The main task of the satellite attitude and orbit control subsystem is to complete the attitude control and orbit control of the satellite from launch to normal in-orbit operation to the end of its life. The satellite electric propulsion subsystem is the executive mechanism of the satellite, which accelerates the working medium carried by electric energy to make it eject at high speed to generate thrust. The timing and direction of thrust generated by the electric propulsion subsystem can be adjusted. This process is completed under the command of the control subsystem. The joint work of the two can realize the orbit control of the satellite. When the electric propulsion subsystem is working in orbit, its thrust adjustment mechanism will be adjusted ...
