Research of System Design in a Hardware-in-the-loop Simulation and Analysis System for Guidance Accuracy

在飞行器控制系统的设计过程中,半实物仿真发挥了重要的作用。特别是在系统设计过程中,转台模型作为整个系统的重点和难点,其性能直接反映了仿真系统的精确度和置信度;三轴仿真测试转台起着很大的考核与验证作用,它有别于传统的三轴转台仿真。本文对三轴仿真测试转台的技术指标,半实物仿真系统的组成、工作原理与实际应用进行了详述。该系统已成功应用于某空间飞行器姿控系统半实物仿真试验中。

Hardware-in-the-loop simulation plays an important part in designing of vehicle control system. Especially in the design of control system, the simulator model is the main part and determines the reliability and the accuracy of this system;It is very crucial in verifying the design of control system for spacecraft and it was different from traditional threeaxis simulator. In this paper, the technical performance, system constitution and application of three-axis air-bearing table in hardware-in-the-loop simulation were particularly described. They were successfully used in some hardware-in-the-loop simulating experiments of attitude control system.
