星载光谱仪转动部件可靠性精确定位 space-borne spectrometer rotating parts high reliability accurate locating

摘要

基于星载差分吸收光谱仪转动部件控制需求,设计了星载光谱仪转动部件的测试系统。采用微动开关复位加定步的电机运动方式实现电机的精确定位。采用脉冲调制(PWM)的方式实现驱动电流的精细调节。并搭建平台对系统进行重复性测试,实验结果表明,测试系统具有较高的可靠性和稳定性,能够满足光谱仪的精确定位要求,使电机在工作寿命内按计划完成定标工作。

Abstract

Based on the need of spaceflight design, a driver of rotating parts of a space-borne spectrometer was designed to accurately control the locating of the three motors. Motor’s accurate positioning is completed by resetting and fixed steps of micro switch. Fine adjustment of driving current is completed by using PWM mode. A platform was built and repeated tests were given to the design. The result showed that the system has high reliability and stability and can fulfill the requirements of accurate locating to make sure that the motors can finish the calibration according to the arrangement.
