TLDR
In this paper, a comprehensive approach to the control of synchronous reluctance machines (SYNCRELs) based on the machine's ideal model is presented. But the effects of saturation and iron losses are briefly considered.Abstract:
This work develops a comprehensive approach to the control of inverter-fed synchronous reluctance machines (SYNCREL), based on the machine's ideal model. From the theory a control simulation is designed. Simulation and experimental results are presented. The effects of saturation and iron losses are briefly considered. >read more

High-grade control of switched reluctance machines
TL;DR: A systematic approach to waveform design is developed, and is evaluated using both simulation and experimental testing of an SR motor servo-drive system, which gives smooth torque operation with maximised torque-speed range or efficiency.

Low-Cost Ferrite PM-Assisted Synchronous Reluctance Machine for Electric Vehicles
Haiwei Cai,Bo Guan,Longya Xu +2 more
TL;DR: An optimally designed ferrite permanent magnet-assisted synchronous reluctance machine (PMaSynRM) is presented to demonstrate its feasibility in electric vehicle applications and can achieve performance very close to that of the benchmark PM machine with much lower costs.
Performanceof FeedforwardCurrentRegulators forField-Oriented Induction Machine Controllers
TL;DR: A modern control theory approach which circumvents limitations of classical control strategies and uses a state-variable feedback control model of the field-oriented induction machine to be intrinsically more robust than PI regulators.

The synchronous reluctance solution: a new alternative in AC drives
TL;DR: In this paper, the synchronous reluctance motor drive is illustrated as a new incoming technology solution and the obtainable performance in terms of torque per volume is compared to that of brushless and induction motors.
The synchronous reluctance solution: a new alternative in A.C. drives
TL;DR: The modern synchronous reluctance motor drive is illustrated as a new incoming technology solution, and the effect of some second-order control aspects are evidenced, together with the possible advantages of adoption of flux-observer based schemes.

Analysis and realization of a pulsewidth modulator based on voltage space vectors
TL;DR: In this article, a space vector concept for deriving the switching times for pulsewidth-modulated voltage source inverters is compared with the conventional sinusoidal concept, which results in lower current harmonics and possibly a higher modulation index.

TL;DR: The degree of success of a computer control application depends mainly on the effectiveness of the algorithm, which is generally designed from plant specifications and desired performance characteristics.

High resolution velocity estimation for all digital, AC servo drives
Robert D. Lorenz,K.W. Van Patten +1 more
TL;DR: In this paper, an approach that optimally estimates the velocity at each sample instant is proposed to reduce the effect of quantized angular resolution on the performance of digital servo drives.
