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。
Based on the principle of attitude control and the basic structure of control system, following the principles of “openness”, “integration” and “modularity”, this paper proposes the establishment of a three-axis The stability of satellite attitude control system simulation universal module library, and through a simulation example to verify the validity of the module library. The library is divided into eight categories of functional modules, including actuator, algebraic gesture determination, common modules, controllers, kinematics and kinematics, sensors, space environment and state estimation posture determination, which can be embedded in the MATLAB platform, easy to use, Moreover, the module library can be continuously expanded and improved to provide a fast and effective method for the design and simulation verification of a three-axis stabilized satellite attitude control system.
