Satellite attitude control ground simulation testing system

Abstract

The invention provides a ground simulation test system for satellite attitude control, comprising: control equipment, simulation equipment and acquisition simulation equipment; the control equipment, simulation equipment and acquisition simulation equipment are all equipped with optical fiber reflection memory cards; Optical fibers are interconnected in pairs to form a closed-loop data flow; control equipment, simulation equipment and acquisition simulation equipment realize multi-data interaction in the closed-loop data flow. The control device is used to design the simulation model according to the satellite to be simulated and tested; to remotely control the simulation device and to collect the simulation device; to save and monitor the interactive data in the closed-loop data stream. The simulation device is used to run the simulation model; the acquisition simulation device is used to simulate the input / output of the signal of the satellite to be simulated and tested or directly collect the signal of the satellite to be simulated and tested when the control device cannot design the simulation model. The invention has universality, super real-time performance, and wide application range, shortens the development cycle, and reduces the research and development cost.

Description

technical field [0001] The invention relates to a satellite attitude control ground simulation test system, in particular to a general-purpose, super-real-time attitude control ground simulation test system applied to micro-nano satellites. Background technique [0002] The attitude control system is one of the most complex subsystems in satellite design. During the development process on the ground, due to the lack of a real space environment, the attitude control system cannot be tested directly, but can only be simulated. The main purpose of satellite attitude control ground simulation test is to discover system defects, verify system design and test product performance. Through the ground simulation test, the feasibility and rationality of the satellite attitude control design in terms of scheme and technical realization can be verified, and the system parameters can be further adjusted and the mathematical models of the components can be improved.
