摘要
Abstract
In satellite technology and applications, the attitude determination and control of satellite is very important. Because of all sorts of interference, the attitude angle and the attitude angular velocity in space often deviates from the setting value, then it will need control and adjustment. The working principle of satellite attitude control system is mainly introduced, and a kind of multi-function card for measuring satellite momentum wheels speed is designed. In this system, a DSP chip TMS320C6713 is used as controller, and adopted XC3S700A which programmed flexibly and sampled fast to measure momentum wheels speed, then the data and control signal will be sent to CPU control system through the PXI interface. After that, it will used for momentum exchange with stars and then control satellite attitude to meet the needs of the specific task. 关键词
