Abstract :
This paper presents a new adaptive control system to control both axes of a vibrational MEMS gyroscope. Here we suppose the rotation rate of gyro is an unknown time-varying parameter, rather than a constant as in current literature. A recently reported polynomial approximation is used to identify the time-varying rotation rate. A Lyapunov approach is employed to attain both of the control and adaptive laws. The simulation results based on Berkeley´s Z-axis gyroscope model verify the controllers.
