减小静电陀螺的漂移率与调整方法

REDUCING DRIFT RATE OF ESG AND TRIMMING METHODS

本文分析了静电陀螺干扰力矩和支承系统一些参数的关系,提出了几种减小陀螺漂移的方法,实验结果表明通过最优精调,可以使静电陀螺的常值漂移减少,甚至到零。 在加速度作用下转子位移引起的干扰力矩是极为重要的一方面,必须增加支承系统的刚度。本文提出并应用Robust调节器使静电支承系统的刚度增加到无穷大,因此所有由于加速度使转子产生位移而形成的干扰力矩都将被消除。

The relations between disturbing torque (DT) and some parameteis of electrostatic suspension system (ESS) have been analyzed. Several methods have been proposed for reducing the drift of ESG. The experiment results have shown that the constant drift of ESG has been reduced even to zero by optimal trimming the ESS.Since significant DT is caused by the displacement of the rotor under the actoin of acceleration, it is necessary to increase the stiffness of ESS. In the ESS, Robust regulator for this purpose has been presented and applied. In the case of practical application the stiffness of ESS can be increased to infinity. Therefore, all DT caused by displacement of rotor under the action of acceleration will be eliminated.
