This thesis investigates controller design on the drive axis of MEMS gyroscopes. To increase the performance of gyros, modeling errors, mechanical imperfections, and sensor parameter changes due to the change of environmental factors should be eliminated. The tracking parameters of the closed loop MEMS gyro is strongly related to the performance of the controller on the drive axis. This controller should be robust to disruptive effects and modeling errors. This study uses “Weighted Feed Forward Controller” and “Proxy Based Sliding Mode Controller” methods to control the drive axis. Weighted Feedforward Controllers are used to change the places of zeros to increase error performance and response time. Both methods are robust to model uncertainty and disruptive effects on simulation environments. However, experiments prove that “Proxy Based Sliding Mode Controller” performance overwhelms the other methods. Sliding Mode Controller and PID controller are implemented to compare both methods is based on simulation and experimental data.

Adaptive Nonlinear Control Combined With Unscented Kalman Filter for Permanent Magnet Synchronous Motor Fed by AC/DC/AC Converter Titaouine, A.; Taibi, D.; Bennis, O.; Benchabane, F.; Boumaraf, R.; Yahia, K. (2011-09-10) In this paper, a adaptive non-linear controller is presented for permanent magnet synchronous motor (PMSM) sensorless drives. The adaptive non-linear controller is designed based on an input-output feedback linearization control technique. The unscented Kalman filter is used to estimate the speed, position and load torque. The PMSM is fed by an indirect power electronics converter. This indirect converter is controlled by a sliding mode technique that enables minimization of harmonics introduced by the line...
Coriolis Vibratory MEMS Gyro Drive Axis Control with Proxy-Based Sliding Mode Controller Ozturk, Derya Unsal; Erkmen, Aydan Müşerref (2022-03-01) MEMS (micro electrical mechanical systems) gyroscopes are used to measure the angular rate in several applications. The performance of a MEMS gyroscope is dependent on more than one factor, such as mechanical imperfections, environmental condition-dependent parameter variations, and mechanical-thermal noises. These factors should be compensated to improve the performance of the MEMS gyroscope. To overcome this compensation problem, a closed-loop control system is one of the solutions. In this paper, a close...
An Optimized Analog Drive-Mode Controller for Vibratory MEMS Gyroscopes Eminoglu, Burak; Alper, Said Emre; Akın, Tayfun (2011-09-07) This paper presents an optimized analytical design procedure for the drive mode analog controllers used in vibratory MEMS gyroscopes. The behaviour of the controller during start-up is analyzed in detail including the effect of the limited voltage swing of the controller circuitry. As a result, an optimum design procedure is developed for controller design, which is also experimentally verified in a practical implementation demonstrating a settling time of only 50msec without any overshoot, for a gyroscope ...
AN AUTOMATIC MODE MATCHING SYSTEM FOR A HIGH Q-FACTOR MEMS GYROSCOPE USING A DECOUPLED PERTURBATION SIGNAL Yesil, F.; Alper, S. E.; Akın, Tayfun (2015-06-25) This paper reports a closed-loop controller system developed for in-run automatic matching of the drive and sense mode resonance frequencies of a MEMS gyroscope with a high quality factor (Q). This is achieved by injecting a perturbation signal to the quadrature cancellation loop, while keeping it decoupled from the angular rate control loop. The new controller is implemented in a CMOS ASIC together with the other sensor control loops, and it is verified to maintain matched-mode state under changing environ...
AN IN-PLANE MEMS GYROSCOPE WITH ADJUSTABLE SENSITIVE AXIS Beşcan, Batuhan; Azgın, Kıvanç; Department of Mechanical Engineering (2021-12-7) This thesis presents the design, fabrication, and test steps of a gyroscope that can perform the maytagging and carouseling without the need for a rotary platform. The sensor has two orthogonal, decoupled, and identical drive axes connected to the same proof mass, and there is a sense axis orthogonal to both of these drive axes. The drive axes can be driven independently; hence, the motion path of the proof mass can be adjusted by adjusting the frequencies, amplitudes and phases of the driving signals. Thus...
