Hardware-in-the-Loop Simulation System for Rapid Validation of High Accuracy Space Orbit Control Mission

针对长周期高精度轨道控制任务的快速仿真试验需要,对传统的卫星控制系统半实物仿真系统进行了重构.提出利用动力学仿真模型程序的超实时运行驱动试验进程加速的方法,介绍系统总体设计思路及其结构、组成和工作原理,给出实时/超实时双模高精度动力学模型的开发及星地状态同步两项关键技术的具体实现,并通过应用实例证明了系统的有效性.

Based on the traditional hardware-in-the-loop （HIL） simulation system of spacecraft attitude and orbit control system （AOCS） , a new simulation system is designed and realized for validation of time-consuming and high accuracy space orbit control mission. In this system, an approach is proposed, which can accelerate process of simulation experimentation by super real-time running of program in dy- namics simulator. The implement planning, structure, components and working principle of the system are introduced. Then the two key problems are detailed, including exploring of the real-time ＆ super re- al-time orbit and attitude dynamics model, and synchronization for states of hardware tested and test e- quipment. The system has been applied for development of AOCS successfully; its validity is illustrated by an instance.
