System Identification of MEMS Vibratory Gyroscope Sensor

الملخص EN

Fabrication defects and perturbations affect the behavior of a vibratory MEMS gyroscope sensor, which makes it difficult to measure the rotation angular rate.

This paper presents a novel adaptive approach that can identify, in an online fashion, angular rate and other system parameters.

The proposed approach develops an online identifier scheme, by rewriting the dynamic model of MEMS gyroscope sensor, that can update the estimator of angular rate adaptively and converge to its true value asymptotically.

The feasibility of the proposed approach is analyzed and proved by Lyapunov's direct method.

Simulation results show the validity and effectiveness of the online identifier.
