MEMS gyroscope challenges
A MEMS (Micro-Elctromechanical System) gyroscope is a sensor measuring angular rates. It is made up of two masses which vibrate orthogonally to each other. The principle is to measure the Coriolis effect which linearly depends on the angular rate. However, this sensor suffers from several disturbances which motivates the use of control techniques in order to increase its accuracy. An accurate model of the sensor dynamics need to be identified in order to yield optimal control performances.
