ABSTRACT:

A vibratory Micro-Electro-Mechanical System (MEMS) gyroscope is a device that can measure angular rate as it is rotated. The uncoupled angular rate sensors can be coupled to enhance their properties. In this research, the focus is on understanding the Nonlinear dynamics underlying the coupled system of MEMS gyroscopes. For this reason, prototype devices have already been fabricated in an open-ended coupling scheme (as a chain). Meanwhile new designs are being explored in a close-ended coupling scheme (as a ring). In the new designs, parametric resonance is being investigated in order to tune one or more control parameters. In this talk, the design process that enables the control and usage of the Nonlinear Dynamics of a MEMS Gyroscope will be presented.
