Abstract

This paper presents a systematic approach in reaching governing equation for microgyroaccelerometer. The study is focused on to analyze the dynamic characteristics of vibratory microgyroaccelerometer. In this device, the mechanical structure is excited into oscillatory motion. The angular velocity input to the sensor is then multiplied by the periodic driven motion. A demodulation is required to recover the angular velocity input and linear acceleration from the sense responses, as the governing differential equations for the Gyroaccelerometer input and output are time variant. The frequency responses for the time variant linear system is obtained through the demodulation and low pass filtered steady-state output to sinusoidal excitation. The frequency response, thus, obtained are validated with MATLAB Simulink data.
