本文提出了一种速率积分微机电系统环形陀螺仪的控制方案，以减小结构缺陷对用于描述陀螺仪结构振动的椭圆进动的影响。提供的建模证明了控制方案实施后陀螺仪测量精度的潜在增加。此外，所使用的陀螺仪动力学的描述提供了驱动失调的影响的替代描述。最后，实验结果表明，所提出的控制方案的可行性。
In this paper, a control scheme is presented for a rate integrating microelectromechanical system ring gyroscope that reduces the effects of structural imperfections on the precession of an ellipse used to describe the structural vibration of the gyroscope. Modeling is provided that demonstrates the potential increase in gyroscope measurement accuracy on implementation of the control scheme. Furthermore, the description of the gyroscope dynamics used provides an alternative description of the effect of drive mistuning. Finally, experimental results are provided that demonstrate the viability of the proposed control scheme.
