Abstract
A frequency modulated (FM) and whole angle (WA) gyroscope have unique properties such as unlimited bandwidth and no temperature sensitivity, therefore it is expected as a next-generation high performance gyroscope.
An independently controlled CW and CCW mode oscillations on a degenerated MEMS resonator is one of the method to realize the FM/WA gyroscope, which can measures both angular rate and rotation angle simultaneously.
In this seminar, I will introduce the basic principle of the CW/CCW mode separation, control system of the FM/WA gyroscope, experimental results and some methods to reduce a mode-mismatch effect.
