摘　　要：卫星控制系统半物理仿真是在实验室中模拟卫星在轨道上运动特性的一种试验方法 ,它通常用于验证卫星控制系统方案和性能指标。卫星控制系统半物理仿真包括将硬件接入路的卫星动力学仿真和运动学仿真。仿真计算机计算卫星的动力学和运动学方程 ;转台模拟卫星在空间的运动 ;目标模拟器用来模拟作为卫星姿态敏感器的参考目标 (太阳、地球和恒星等 )的环境特性。为了将控制系统硬件接入试验路 ,必须适当地处理一系列的关键技术。卫星控制系统多转台多模拟器半物理仿真方法适用于带有多种敏感器的复杂卫星仿真。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.
