Problems solved by technology

Existing satellites generally use two-axis SADA to realize sailboard orientation to the sun, and the control algorithm strategy is complicated. At the same time, SADA itself has Hall sensors and slip rings, which have the defects of complex structure and high cost, which is not conducive to the demand for mass production of satellites.

Abstract

The invention discloses a swing type single-shaft SADA control method. The method comprises the following steps: respectively arranging travel switches on mechanical limiters on two sides of an SADA structure, and simultaneously arranging soft limiters on the angle of a rotating shaft in SADA control software; constructing an SADA on-orbit working mode according to the charging requirement of on-orbit operation of a star; after the star enters the three-axis ground, starting a capturing mode to rapidly capture the sun, and switching to a tracking mode when the angle meets a preset target; when the star executes a task, starting a holding mode; when the star needs to be in a long-term sun-facing state, starting a constant-angle keeping mode; if the angle data of the SADA is in an uncalibrated state, starting a calibration mode to recapture the angle; and when the rotating shaft of the SADA at a certain side fails, starting a fault mode at the current side, and not carrying out calculation and control any more. According to the method, a sun-synchronous orbit type satellite can control the SADA to stably track the sun azimuth for a long time, sun orientation of a solar panel is achieved, and on-satellite energy balance is met.

Description

technical field [0001] The invention relates to the technical field of satellite attitude determination and control, in particular to a swinging single-axis SADA control method. Background technique [0002] Long-term three-axis ground-to-ground satellites need Solar Array Drive Assembly (SADA) to drive solar panels to align with the sun to meet the energy balance on the planet. Existing satellites generally use two-axis SADA to realize sailboard orientation to the sun, and the control algorithm strategy is complicated. At the same time, SADA itself has Hall sensors and slip rings, which have the defects of complex structure and high cost, which is not conducive to the demand for mass production of satellites. . Contents of the invention [0003] The present invention aims to solve one of the technical problems in the related art at least to a certain extent. [0004] For this reason, the object of the present invention is to propose a swing type single-axis SADA control...
