Abstract
This paper presents a new design approach of the automatic gain control (AGC) loop in driving mode of MEMS gyroscopes. The designed control loop suggests that the system can maintain constant velocity output under variations of mechanical parameters. Moreover, the proposed method gives us more systematic approach and precise results. From the analysis it is shown that the proposed loop is absolutely stable for all kind of parameter variations. The simulations and experiments show that the automatic gain control loop is successfully applied to the control of drive oscillation mode of the MEMS gyroscope.
