A Ground Simulation System for Satellite Attitude Control Based on Plug and Play Technology

Abstract

A satellite attitude control ground simulation system based on plug-and-play technology, including an air bearing turntable, an embedded attitude control unit, a plug-and-play component, a ground control unit and a display device; the plug-and-play component has an intelligent interface The satellite-borne equipment of the unit, the embedded attitude control unit receives the measurement data output by the sensor component, calculates the satellite attitude and sends the control command output to the execution unit, and at the same time sends the real-time attitude information to the ground control unit; the ground control unit receives the embedded attitude control The real-time attitude information sent by the unit is stored, and the satellite attitude information and the measurement data output by the sensor components are displayed on the display device in real time, so as to observe and monitor the operation process of the simulation system. The invention has strong versatility, reduces repeated design at the hardware level of the system, and can be used for new applications only by making certain modifications on the software, thereby shortening the research and development cycle and cost.

Description

technical field [0001] The invention relates to the field of satellite attitude control system testing, in particular to a ground simulation system for small satellite attitude control testing based on plug-and-play technology. Background technique [0002] Attitude control is a highly complex system in satellite design, and its stability and reliability are self-evident. In the process of satellite development, in order to ensure that the satellite can operate normally in accordance with the design requirements in the real space environment after launch, a large number of simulation tests have to be carried out on the ground. The semi-physical simulation of the spacecraft control system is one of them. It uses the air bearing turntable as a motion simulator and combines some real objects to build a semi-physical simulation environment to provide simulation verification for satellite attitude control schemes and algorithms. The air-floating turntable floats the platform in ...
