2009 IEEE Symposium on Industrial Electronics & Applications, 2009
This paper deals with two popular and powerful methods in electrical drive applications. The first one is the field oriented control (FOC) and the other one is space vector modulation (SVM). The proposed FOC-SVM method is incorporated with a predictive current control (PCC) technique.

Two-phase VSI inverter using space vector modulation for field oriented DSM drive
International Symposium on Power Electronics Power Electronics, Electrical Drives, Automation and Motion, 2012The paper deals with space vector pulse width modulation (SVPWM) technique for vector controlled of two-phase disk synchronous machine (TPDSM). It is supposed that machine is supplied by VSI three-leg inverter. A reference voltage vector located in the irregular hexagon is realized by adjusting six space vectors and two zero vectors.

Harmonic and Killing Vector Fields in Compact Orientable Riemannian Spaces with Boundary
The Annals of Mathematics, 1959Publisher Summary This chapter presents the results on harmonic and killing vector fields to the case of Riemannian spaces with boundary. The harmonic tensors on such Riemannian spaces are studied, and the relations between curvature and relative Betti numbers in Riemannian spaces with boundary are discussed.

A New Approach For Constructing A Vector-Oriented Control Theory By State Space Method
SPIE Proceedings, 1987This paper presents a new attractive approach for a vector control system of AC machine by state space method. First state equations of an induction machine suitable for the current control are derived. It becomes clear that the induction machine can be described as three input-three output controlled object.

Voltage oriented control of three phase PWM rectifier with Bus Clamped Space Vector PWM
2015 International Conference on Power, Instrumentation, Control and Computing (PICC), 2015Pulse Width Modulated (PWM) Rectifiers have gained the popularity during recent years for the ac to dc conversion needs of the industry, customer and power grid sectors. This bidirectional convereter can acts as an ac to dc boost rectifier with near unity power factor at the grid side along with regulated and ripple free dc voltage at the output.

A novel space-vector current regulation scheme for a field-oriented-controlled induction motor drive
IEEE Transactions on Industrial Electronics, 1998The system performance of an AC variable-speed drive directly depends on the current regulation. In this paper, a novel space-vector current regulation scheme for a field-oriented controller (FOC) is developed. Motor currents are regulated by generating appropriate inverter output voltage vectors via software-implemented comparators and a switching ...

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 ...

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 ...

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 ...
