摘要
为提高陀螺仪的精度,采用壳体翻滚自动补偿与壳体有关的漂移误差力矩。介绍了一种无刷直流伺服电动机数字控制系统,并与俄罗斯Д-15仪表的模拟控制系统做了比较。同时在运动件和固定件之间设计了一套特殊的导电装置。实验表明该导电装置使用寿命长、可靠性高。
In order to improve the precision of gyroscope, case rotation is usually applied to automatically compensate drift error torque relative to the case. The paper introduces a kind of Brushless DC-Servomotor＇s numeric control system and makes comparison with Russian д-15 analog control system. At the same time, a special conductive device is designed between moving module and immobile shell. The result of experiment shows that the conductive device has longevity of service and high reliability.
