摘要
介绍了一种基于双余度混合式步进电动机的双自由度卫星天线运动控制系统。系统采用89C 196KC单片机和多极旋转变压器实现了卫星天线指向系统的位置伺服控制。介绍了系统工作原理、89C 196KC及其外围硬件电路、细分与预置步数控制、角位置检测、精确归零及断电定位控制。该控制方法提高了系统的定位力矩。
This paper introduces a double freedom degree motion control system of satellites antenna based on dual -redundancy hybrid stepping motor. The 16-bits single- chip computer （89C196KC）and resolver are used to realize the position servo control of antenna pointing system. The operation principle of system, peripheral hardware circuits of 80C196, fractionized and prearranged control of stepping number, angle position measure, accurate return-to-zero of position and orientation control after power-off are discussed.
