Abstract

The paper presents theoretical and numerical study of a MEMS vibration gyro based Coriolis effect. Two configurations of the gyro are modeled and simulated here: 1) with assumed control on the excitation axis (a simplified configuration used to validate the second one); and 2) gyro controlled on the excitation axis. Shown are: general dynamic equations of the gyrometer, mathematical models ant the resulted block diagrams for the two configurations, the control strategy for the second configuration, software implementations of the models and numerical simulations results.
小型陀螺仪的建模与仿真
本文对基于科里奥利效应的微机电系统振动陀螺进行了理论和数值研究。本文对陀螺的两种结构进行了建模和仿真:1)假设对激励轴进行控制(用于验证第二种结构的简化结构);2)陀螺控制在激励轴上。给出了陀螺仪的一般动力学方程,两种结构的数学模型和框图,第二种结构的控制策略,模型的软件实现和数值仿真结果。
