Abstract

Behavioral level simulations are a quick and efficient (reliable) technique to analyze the behavior of complex electro-mechanical systems. In the present work a Simulink model of the gyro-accelerometer system has been built using behavioral building blocks and behavioral simulations are executed to analyze the frequency response and transient behavior of the system. The mechanical part of the Simulink model is interfaced with suitable blocks and circuits for discrimination of acceleration and gyro action that occur simultaneously in the gyro-accelerometer output. With a given value of mass, spring stiffness and damping coefficient, the characteristic equations of motion expressed in s-domain can be easily solved by Simulink model in a few minutes.
