In this study, it is aimed to increase the bandwidth frequency of an electromechanical control actuation system by Coulomb friction compensation method. The actuation system consists of a brushless direct current motor, ball screw and lever mechanism. Both linear and nonlinear mathematical models of the system were obtained. The non-linear model was confirmed by real-time testing of a prototype. The friction torque coefficient of the prototype and the Coulomb friction torque due to its angular position were obtained. The found Coulomb friction torque profile was then used in real-time tests as friction compensation. As a result, it has been seen that the system's bandwidth frequency can be increased by 12% with Coulomb friction compensation method.

Adaptive control of DC link current in current source converter based STATCOM for improving its power losses
Karaduman, Ferdi; Ermiş, Muammer; Bilgin, Hazım Faruk; Department of Electrical and Electronics Engineering (2012)
In conventional three-phase PWM (Pulse Width Modulation) current source converter based STATCOM (Static Synchronous Compensator) applications, DC link current is kept constant at a predefined value and the reactive power of STATCOM is controlled by varying modulation index. This control strategy causes unnecessary power losses especially when the reactive power of STATCOM is low. For this purpose, in order to reduce the active power drawn by STATCOM, the modulation index can be maximized by adjusting DC lin...
Improving the efficiency of microwave power amplifiers without linearity degradation using load and bias tuning in a new configuration
Ronaghzadeh, Amin; Demir, Şimşek; Department of Electrical and Electronics Engineering (2013)
Advanced digital modulation schemes used in the wireless applications, result in the modulated RF signals with high peak to average power ratio which requires linear amplification. On the other hand, the demand for a longer talk time with less battery volume and weight, especially in hand-held radio units, necessitate more power efficient methods to be utilized in power amplifier design. But improved linearity and efficiency have always been contradicting requirements demanding innovative power amplifier and...
High performance closed-loop analog readout circuit for capacitive MEMS accelerometers
Terzioğlu, Yunus; Akın, Tayfun; Department of Electrical and Electronics Engineering (2015)
In this thesis, a closed-loop analog readout circuit for capacitive MEMS accelerometers is introduced. The detailed analysis of the dynamics of the proposed accelerometer is presented along with the associated simulation models. The theoretical investigation of each building block of the accelerometer is also presented in detail and supported by the corresponding formulas. The implemented accelerometer is shown to satisfy the estimated performance parameters with measurements conducted using various test se...
A High performance automatic mode-matched MEMS gyroscope
Sönmezoğlu, Soner; Demir, Şimşek; Department of Electrical and Electronics Engineering (2012)
This thesis, for the first time in the literature, presents an automatic mode-matching system that uses the phase relationships between the residual quadrature and drive signals in a gyroscope to achieve and maintain the frequency matching condition, and also the system allows controlling the system bandwidth by adjusting the closed loop parameters of the sense mode controller, independently from the mechanical sensor bandwidth. There are two mode-matching methods, using the proposed mode-matching system, p...
High-Performance Harmonic Isolation and Load Voltage Regulation of the Three-Phase Series Active Filter Utilizing the Waveform Reconstruction Method
Senturk, Osman S.; Hava, Ahmet Masum (Institute of Electrical and Electronics Engineers (IEEE), 2009-11-01)
This paper develops a waveform reconstruction method (WRM) for high accuracy and bandwidth signal decomposition of voltage-harmonic-type three-phase diode rectifier load voltage into its harmonic and fundamental components, which are utilized in the series active filter (SAF) control algorithms. The SAF-compensated system utilizing WRM provides high-performance load harmonic voltage isolation and load voltage regulation at steady-state and during transients compared to the system utilizing the synchronous r...
