A frequency modulated (FM) and rate integrating (RI) gyroscope has unique properties such as unlimited bandwidth, excellent linearity 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 methods to realize the FM/RI gyroscope, which can measures both angular rate and rotation angle simultaneously. This method can completely eliminate the temperature dependency of the material (Silicon), and has a potential of quite large bandwidth. In addition, the frequency and quality factor mismatch, which causes measurement error, can be easily compensated by this technique.
In this seminar, the speaker will introduce the basic principle of the CW/CCW mode separation, control system of the FM/RI gyroscope, experimental results and some methods to reduce a mode-mismatch effect.
