Multi-tables and Multi-simulators Semi-physical Simulation Method for Satellite Control System

Semi-physical simulation of control syst em s for satellites is a test method in laboratory for simulating satellite movemen t in orbit. It is used to validate the design and performance specifications of control system of satellite. The Semi-physical simulation of control systems f or satellites consists of dynamics simulation and kinematics simulation of satel lite with hardware in the loop. The simulation computer calculates dynamics and kinematics equations of the satellite and the turntables simulate movement of th e satellite in space. Target simulators are used to simulate the environment cha racter of reference objects (the sun, the earth and stars) as satellite attitude sensors. In order to connect the hardware of control system to the test loop, i t is necessary to treat with a series of key techniques properly. Multi-tables and multi-simulators Semi-physical simulation method for satellite control sys tems is applied to simulation of complex satellite with multi-sensors.
