This paper proposes a self-splitting fuzzy classifier with support vector learning in expanded high-order consequent space (SFC-SVHC) for classification accuracy improvement. The SFC-SVHC expands the rule-mapped consequent space of a first-order Takagi-Sugeno (TS)-type fuzzy system by including high-order terms to enhance the rule discrimination ...

An Improved Rotor Flux Space Vector Based MRAS for Field-Oriented Control of Induction Motor Drives
IEEE Transactions on Power Electronics, 2018The paper proposes an improved low speed performance of classical rotor flux (RF)-based model reference adaptive system (MRAS) for field oriented controlled induction motor (IM) drives. The improved performance of the RF-MRAS estimator is obtained by using voltage reference vector to compute the rotor flux vector in the reference model instead of ...

Phase back EMF space vector oriented control of brushless DC motor for torque ripple minimization
2016 IEEE 8th International Power Electronics and Motion Control Conference (IPEMC-ECCE Asia), 2016As the back-EMF of the BLDCM is not sinusoidal, the change of back EMF in time axis dose not synchronize with the rotor position, and it's more difficulty to convert the back-EMF from time axis to space axis. This paper starts from the non-sinusoidal change law of the back-EMF of the BLDCM, and introduces the back-EMF space vector, then obtains the ...

Space vector based synchronized PWM strategies for field oriented control of VSI fed induction motor
2016 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2016The space vector approach in real time pulse width modulation offers variety of switching patterns for effective control of induction motor drives. In high power motor drives switching frequency of the inverter is very less due to increased losses. The harmonic distortion in the stator current due to low switching frequency can be reduced by using ...

Field oriented space vector pulse width modulation control of permanent magnet brushless DC motor
2017 IEEE Region 10 Humanitarian Technology Conference (R10-HTC), 2017This paper describes the field oriented control strategy for permanent magnet brushless DC motor with space vector pulse width modulation technique using current sensor and a speed sensor as feedback. Adaptive proportional-integral (PI) controller is introduced in this proposed control method.

In this paper, a field oriented control of Permanent Magnet Synchronous motor fed from a 3-level Neutral point clamped (NPC) inverter is investigated. With the Space vector modulation (SVM) control, the dc-link capacitors are operated in balanced condition and a true 3-level operation is obtained.

2019 International Conference of Computer Science and Renewable Energies (ICCSRE), 2019
This paper relates to the works on the control and the identification of multiphase motors flux applied on electric ship propulsion. It describes a vector control namely the Field Oriented Control (FOC) strategy using Four-Vector 24-Sector Modulation (FV24SM) based on VSD method (Vector Space Decomposition).

In this work a field oriented control (FOC) method is used, in combination with a multilevel inverter, in order to control the speed of an induction machine. A three level diode clamped inverter (DCI) is used, instead of a cascaded multilevel inverter which is the usual solution.
