Abstract

The invention discloses a satellite thrust eccentric torque control device and method. The device comprises a bottom plate, a controller, a mass block, a first direction driving unit, a second direction driving unit and an angular velocity measuring unit. The controller, the mass block, the first direction driving unit and the second direction driving unit are arranged on the bottom plate. The mass block is driven by the first direction driving unit and/or the second direction driving unit to move in a first direction and/or a second direction. The angular velocity measuring unit is used for measuring an angular velocity parameter of a satellite and sending the angular velocity parameter to the controller. The controller is used for controlling the first direction driving unit and/or the second direction driving unit to act according to the angular velocity parameter. According to the satellite thrust eccentric torque control device and method, the mass center position is changed by moving the mass block to move, the thrust vector torque is made to penetrate through the mass center, eccentric torque is eliminated, and influences of a propelling system on the satellite posture are reduced; and the algorithm structure is simple, and the controller is high in reliability.

Description

technical field [0001] The invention relates to the technical field of spacecraft control, in particular to a satellite thrust eccentric moment control device and method. Background technique [0002] With the development of aerospace technology, the number of spacecraft launched by various countries is increasing, causing space resources to become more and more tense. With the increasing demand for spacecraft formation networking and constellation missions, the dependence of spacecraft on propulsion systems is increasing. At the same time, due to the increasing number of failed spacecraft, a large amount of space junk has been caused, which has brought huge risks to space missions. Therefore, my country stipulates that starting from 2020, all spacecraft launched into orbit must be equipped with de-orbit devices. , can actively deorbit at the end of its life. The current deorbiting measures mainly include the thrust system and deorbiting sails. Off-orbit sails are mainly u...
