【摘要】 航天器仿真技术作为现代航天工程的关键技术,是实现航天器所担负航天任务的重要保证。因此,在姿态确定、姿态控制和姿态动力学等建模基础上,建立高性能的航天器姿态控制仿真系统是航天器控制系统设计的重要内容。本文对航天器姿态控制仿真系统进行了深入的研究,主要内容如下:首先,对航天器姿态控制系统进行了整体的研究,总结了其中组件的性能指标、发展状况和类型信息等经验知识。此外,根据实际需求,重点对部分常用的组件进行了数学建模。其次,制定了航天器姿态控制仿真系统的接口规范,建立了组件仿真模型,并通过计算实例对比分析了数学模型与仿真模型的误差,验证了仿真模型的有效性。最后,采用组件技术建立了航天器姿态控制系统仿真平台,并根据对地定向的近地圆轨道卫星仿真任务的要求,利用仿真平台建立了该仿真任务对应的卫星姿态控制仿真系统,验证了仿真平台的可行性。更多还原

【Abstract】 As a key technology of modern space engineering, spacecraft simulation technology is a significant guarantee to accomplish the space tasks of spacecrafts. Therefore, based on the modeling of attitude determination, attitude control and attitude dynamics, the main content of spacecraft control system design is to establish a high-performance simulation system of spacecraft attitude control.An in-depth research on the simulation platform of spacecraft attitude control system has been done in this paper, and its contents are as follows.Firstly, an overall analysis has been made on the spacecraft attitude control system in this paper. The performance data, development situation, type information and other design information of the components in the control system are summed up. In addition, this part also focuses on the mathematical modeling of part of the components that are often used according to actual need.Secondly, the interface standards of the simulation system for spacecraft attitude controlling are formulated, and the simulation models of the components are established. By analyzing the errors resulting from comparing the mathematical model and simulation model in real calculation examples, we can verify the validity of the simulation model.Finally yet importantly, with the help of component technology, I establish the simulation platform for the spacecraft attitude control system. In addition, according to the simulation task requirements of near-earth satellites with circular orbit that move around the earth, we can set up the simulation system for satellite attitude controlling according to real simulation tasks, and then verify the feasibility of the simulation platform.更多还原
