A researsh on rotational error calculation of mobile solar simulators and elimination method

移动式太阳模拟器主要应用于太阳敏感器的模拟试验、性能测试与标定。通过对其两维平移和转动机构的控制,为太阳敏感器提供精确位置的光信号。本文通过理论计算并应用基于圆感应同步器的反馈控制系统来消除转动机构中涡轮蜗杆传动的空回误差角,来达到传动精度要求。

Mobile solar simulators are mainly used in simulative experiment, capability test and demarcation of sun sensors. It presents the light signal with precise position for sun sensors through controlling two-dimensional translation and rotation gears. The paper, through theoretical calculations, uses feedback controlling system based on round inductosyn to eliminat transmission backlash errors of worm gearing in rotation mechanism to satisfy the required precision of transimission.
