Abstract
MEMS vibratory gyroscopes are widely used in various fields such as consumer electronics, automotive industry, and navigation systems owing to their merits of low power, low cost, and small volume. A MEMS gyroscope is one of the most important inertial devices, which is researched all over the world.
This chapter will introduce a MEMS vibratory gyroscope, aiming to make more people understand what it is and how it works. Firstly, structure design and fabrication, as well as its dynamics theory, are illustrated. Secondly, closed-loop control for the drive mode and mode-matching control are demonstrated. Finally, closed-loop control for the sense mode, followed by temperature compensation method, is presented in detail. In addition, theoretical deduction, simulation, and experimental tests are combined tightly to make the proposed techniques understand easily.
