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...

Problems solved by technology

General terrestrial wireless ad hoc network routing protocols usually have to deal with complex and changeable node topologies. The large number of nodes and frequent and uncertain topological changes between nodes greatly increase the difficulty of realizing terrestrial wireless ad hoc networks; and the satellite attitude The control simulation system usually has a small number of nodes (generally within tens) and the relative position of the nodes basically does not change during the test process, and only needs to be responsible for dealing with the topology changes caused by node movement and removal (including node failure)
