Space-time vector delta-sigma modulation
2002 IEEE International Symposium on Circuits and Systems. Proceedings (Cat. No.02CH37353), 2003Classical delta-sigma modulation gains resolution through temporal oversampling by using a high-speed, low-resolution quantizer and shaping the resulting quantization errors out of the signal band. Likewise, spatial delta-sigma modulation is often used in image halftoning to create high-visual-quality binary images.

Modules at last! In most books on a similar subject modules appear on the very first pages. And there are good reasons for this. Ring theory and module theory are symbiotic. Many questions about rings can be handled most effectively by using modules. Moreover, sometimes modules seem to be inevitable.

Space Vector Modulation for Multiphase Inverters Based on a Space Partitioning Algorithm
IEEE Transactions on Industrial Electronics, 2009Since the late 1990s, multiphase drives have become a serious alternative to three-phase drives in some particular applications such as electric ship propulsion, locomotive traction, electric vehicles, and high-power industrial applications. Nowadays, the research activity is focused on the development of control strategies that can exploit the degrees

Discrete Space Vector Modulation Applied on a PMSM Motor
2006 12th International Power Electronics and Motion Control Conference, 2006The Permanent Magnet Synchronous Motors (PMSM) are extensively used in high-performance industrial applications. The electromagnetic torque in a PMSM is proportional to the angle between the stator and rotor flux linkages. Therefore, high dynamic response can be achieved by means of Direct Torque Control (DTC).

Linearization of Over-Modulation in Dodecagonal Space Vector PWM
2019 IEEE 28th International Symposium on Industrial Electronics (ISIE), 2019Growing commercial acceptance of electric vehicles (EV) resulted in increased focus on the development of technologies associated with it. This includes research on vehicle charging systems, traction inverters and motors, transmission systems, cooling mechanisms to name a few.

If vector spaces are projective modules then multiple choice holds
MLQ, 2005Summary: We show that the assertion that every vector space is a projective module implies the axiom of multiple choice and that the reverse implication does not hold in set theory weakened to permit the existence of atoms.

Space Vector Modulated Direct Torque Control for PMSM
2011It always exists that there are big ripples on flux linkage and electromagnet torque in traditional direct torque control (DTC) system. The implement of space vector modulation (SVM) was researched in-depth. The optimum combination of the fundamental voltage space vector was obtained according to the current expected voltage vector so as to compensate ...
