Description

technical field [0001] The invention belongs to the technical field of spacecraft simulation testing, and in particular relates to a semi-physical simulation system for spacecraft attitude control of a wireless self-organizing network. Background technique [0002] The satellite attitude control system occupies a very important position in the design of the satellite control system, so the simulation of the attitude control system has very important practical significance for speeding up the research progress of the satellite control system, shortening the development cycle, and improving the reliability of the control system. The semi-physical simulation is based on the full mathematical simulation, by introducing the on-board computer and the sensors and actuators that need to be considered into the control loop, and the other parts still use mathematical simulation. [0003] The traditional simulation system design method is to connect the sensors, on-board computer and a...
