摘　　要：研究卫星姿控系统快速建模问题,根据姿态控制原理以及控制系统的基本结构,遵循"开放性"、"集成性"和"模块化"等原则,提出建立了三轴稳定卫星姿态控制系统仿真通用模块库,并通过一个仿真算例验证了模块库的有效性。该库划分为执行机构、代数法姿态确定、常用模块、控制器、动力学与运动学、敏感器、空间环境和状态估计姿态确定等八大类功能模块,可嵌入到MATLAB平台中,使用方便,而且可以对模块库不断扩展改进,为三轴稳定卫星姿态控制系统设计与仿真验证提供了一个快速有效方法。According to the principle and the structure of 3-axis stable satellite attitude control system, a unitized MATLAB/Simulink modules library for 3-axis stable satellite attitude control system was build to resolve the problem of fleetly modeling. It was designed following three rules ： openness, integration and modularization, then its validity was proved by a simulation example. The library can be embedded into the platform of MATLAB/Simulink, which in- eludes eight blocks： Actuators, Algebra AD Blocks, Commonly Used Blocks, Controllers, Dynamics and Kinemat-ics, Sensor Models, Space Environment Blocks and State Estimation Blocks. So it is easy to use and can be serially improved. This method will be helpful for 3-axis stable satellite attitude control system design and simulation.
