“…Most of the MEMS gyroscopes are vibratory-rate gyroscopes that have structures fabricated on crystal silicon or a polysilicon, so they are compact and cost-effective with low power consumption, and they have been developed and applied in many areas, such as consumer electronics, automotive applications, GPS augmentation and a wide range of new military applications [1,2].…”

Microelectromechanical systems (MEMSs) pose unique measurement and control problems compared with conventional ones because of their small size, low cost, and low power consumption. The vibrating gyroscope is one of those MEMS devices that have significant potential in many industry applications. When the MEMS gyroscope system is considered simultaneously with the coupling terms, the exogenous disturbances and the parameter variations, the controller design of this system becomes very challenging. This paper investigates the primary control problem of a perturbed vibrating MEMS gyroscope. A nonlinear robust adaptive control scheme is proposed for the drive axis of a vibrating MEMS gyroscope. By combining the dynamic surface control (DSC) method with the H-infinity disturbance attenuation technique, a simpler systematic design procedure is developed. The derived H-infinity controller has a simplified structure, and it can drive the drive axis to resonance, regulate the output amplitude of the drive axis to a desired value, and attenuate the generalized disturbances. The features of the derived controller are discussed and illustrated by the simulation of a closed-loop system. The analysis and simulation show that the obtained controller possesses good adaptability and robustness to system uncertainties.

“…Advances in micro-electromechanical sensors (MEMS) have led to significant developments in low-cost inertial technology in the last decade (Barbour & Schmidt, 2001). Because of the ongoing development, these sensors are improving (reductions in size, weight and sensitivity) and becoming cheaper due to mass production.…”

“…IMU is used in wide areas not only in transportation vehicles but also in personal goods such as mobile phones, game consoles, and cleaning robots. [1][2][3] Due to the high demands for IMU in many areas, Micro Electro-Mechanical System (MEMS) based IMUs, characterized by the small size, light weight, and low power consumptions, have been increasingly used these days since they can be mass-produced. 1,4 Although the MEMS sensors are produced in mass-production by a same process, each sensor unit has its own characteristics.…”

A new method is presented to calibrate a low-quality, MEMS-based Inertial Measurement Unit (IMU).The proposed method consists of a novel dynamic test-setup with a combination of a single-axis rate-table and an attitude change mount, to overcome the limitations in the conventional calibrations with the static or quasi-static test-setups. A Fourier Transform method is deployed in the proposed scheme to estimate the error parameters including bias, scale factor, and misalignment of the accelerometers and rate gyros. Compared to the commonly used Recursive Least Squares method, the Fourier Transform method is more efficient in terms of the computation time, yet it resulted in comparable or improved results in the series of verification tests in this study.
