摘要
简要介绍我国返回式卫星上用的计算机数字姿态控制系统的方案;重点阐述姿态确定和相平面控制律的设计方法;最后简述飞行试验的结果。
In this paper the digital computer attitude determination and control system used in chinese returnable satellite for scientific exploration and technical experiments is described.The attitude determination algorithm and the jet control logic in phase plane are the major contents of this paper. The concept of quasi-steady gain matrix is introduced for periodic filtering system and a simplfied filtering algorithm has been developed. In the digital autopilot the variable step deadband control logic is developed and it remarkably improves the control quality. Some flight data are presented.The control system performed successfully in the flight test.
