This study focused on a control system of the nonlinear micro-electro-mechanical systems (MEMS) gyroscope. First, sector nonlinearity was used to model MEMS gyroscope in Takagi-Sugeno (T-S) fuzzy system. Second, state observer designed based linear matrix inequality (LMI) identify optimal eigenvalues tracking error function. Then, full-state fixed-time sliding mode (FTSMC) constructed Third, ca...

The replacement of force sensitive resistors (FSRs) with a single vibratory gyroscope has been examined for use within a drop foot correction system. The sensor is small and lightweight enough to be easily attached to the shoe, and may be used (currently with an IBM compatible PC) to detect four gait events: heel contact, foot flat, heel rise and toe off. The cost of the gyroscopic sensor is co...

Satellites based on microelectromechanical system (MEMS) technology and tailored to low-cost space missions are investigated to determine their characteristics and feasibility. This work explores an alternative chassis formed from a stack of microfabricated silicon wafers. The outer layers contain optical sensing, micropropulsion and power generation systems whereas internal layers contain comp...

The combination of multiaxis and multiparameter microelectromechanical systems (MEMS) in the same technology would result in very cheap and smart inertial measurement units (IMUs). In this paper, a Z-axis Lorentz-force-based magnetometer whose design and optimization are reviewed taking into account the constraints of an industrial MEMS technology (process and packaging) already used for accele...

Readout Circuits for Frequency-Modulated Gyroscopes by Igor Igorevich Izyumin Doctor of Philosophy in Engineering – Electrical Engineering and Computer Sciences University of California, Berkeley Professor Bernhard E. Boser, Chair In recent years, MEMS gyroscopes have become nearly omnipresent. From their origins in automotive stability control systems, these sensors have migrated to a diverse ...
