This paper shows temperature and acceleration effects on Micro-Electro-Mechanical-Systems (MEMS) gyroscope and a practical solution is presented to mitigate effect of these errors using different methods (Polynomial Curve fitting and Neural Networks). Compensation is performed on the output bias drift data acquired from different MEMS gyroscopes. Performance of compensation techniques is also presented in this study. This paper presents novelty of integrated compensation for both factors (temperature and acceleration) based on empirical data. The compensation is applied on data acquired from ADIS16488, ADXRS450, and XSENS MTi-10 (commercial sensors from Analog Devices and XSENS). 20% improvement in the bias instability is achieved after temperature compensation in ADXRS450 and 50% improvement in XSENS MTi-10 sensors' data. The compensation techniques significantly reduce the rate random walk. The integration time can be increased 4 times for ADIS16488 and ADXRS450 sensors and 8 times for XSENS MTi-10 sensor. The offset present in MEMS gyroscope can also be reduced from 0.05 degrees/sec to 0.001 degrees/sec (50 times improvement) using integrated compensation as compared to 10 times improvement seen by conventional compensation (temperature only) in the XSENS sensor data.

Compensation of Dead-time Effects in Three-level Neutral Point Clamped Inverters based on Space Vector PWM Mese, Huseyin; Ersak, Aydın (2011-09-10) hi this study the effects of dead-time in three-level neutral-point-clamped (NYC) inverter is analyzed and a compensation algorithm based on space vector pulse width modulation (PWJI) is proposed. In three phase inverter applications, different modulation techniques are utilized depending on the application. Among these, space vector pulse width modulation (SVPWM) technique is the modulation technique with which best bus bar utilization is achieved. This modulation technique is also applicable to three-leve...
Compensation of Nonlinear Effects in Three-level Neutral-Point-Clamped Inverters Based on Field Oriented Control Mese, Huseyin; Ersak, Aydın (2012-09-06) In this paper, the nonlinear effects in three-level neutral-point-clamped inverters will be studied and a compensation algorithm, based on field oriented control (FOC) technique, will be proposed. In voltage source inverters (VSIs), nonlinear effects such as voltage drops on power semiconductors, and their turn on/turn off times cause distortions at the output voltage. Also dead-time, inserted in order to avoid short-circuits, are another source of nonlinearity. The proposed compensation algorithm is develo...
Temperature compensation of a capacitive mems accelerometer by using a mems oscillator Kose, Talha; Azgın, Kıvanç; Akın, Tayfun (2016-02-25) This study reports a temperature compensation method for a capacitive MEMS accelerometer by using a MEMS double-ended-tuning-fork (DETF) resonator integrated with the accelerometer structure on the same die. The proposed method utilizes the frequency information of the clamped-clamped DETF resonator which is oscillating in a closed-loop operation. In order to compensate the temperature dependence of the accelerometer output, frequency drift of the DETF resonator against changing temperature is used, i. e., ...
Correction of temperature and acceleration effects on MEMS gyro output signals / Ali, Muhammad; Akın, Tayfun; Azgın, Kıvanç; Department of Electrical and Electronics Engineering (2014) The scope of this thesis is to study the effects of temperature and acceleration on a MEMS gyroscope and present a workable solution to compensate these errors using various techniques. Compensation for errors is implemented considering the output bias data of the gyroscope. The study also provides comparison of these various techniques, namely Polynomial Curve fitting and Neural Networks. In addition, Moving Average Filtering is used as an auxiliary technique. The study provides novelty of compensating bot...
Optimization of Power Conversion Efficiency in Threshold Self-Compensated UHF Rectifiers With Charge Conservation Principle Gharehbaghi, Kaveh; KOÇER, FATİH; Külah, Haluk (2017-09-01) This paper presents a compact model for threshold self-compensated rectifiers that can be used to optimize circuit parameters early in the design phase instead of time-consuming transient simulations. A design procedure is presented for finding the optimum aspect ratio of transistors used in the converter and number of rectifying stages to achieve the maximum power conversion efficiency. In the presented analysis, the relation between the power conversion efficiency and the load current over the variation o...
