Modeling, simulation, and analysis of permanent-magnet motor drives. I. The permanent-magnet synchronous motor drive
Pragasen Pillay,R. Krishnan +1 more
TL;DR: The application of vector control to the PMSM (permanent-magnet synchronous motor) is described, and complete modeling, simulation, and analysis of the drive system are presented.
Journal ArticleDOI
Modeling, simulation, and analysis of permanent-magnet motor drives. II. The brushless DC motor drive
Pragasen Pillay,R. Krishnan +1 more
TL;DR: A phase variable model of the BDCM is developed and used to examine the performance of a BDCm speed servo drive system when fed by hysteresis and pulsewidth-modulated (PWM) current controllers, indicating that the small- and large-signal responses are very similar.
Journal ArticleDOI
Modeling of permanent magnet motor drives
Pragasen Pillay,R. Krishnan +1 more
TL;DR: In this article, the authors derived the d, q model of the permanent magnet synchronous motor (PMSM) from the well-known synchronous machine with the equations of the damper windings and field current dynamics removed.
Journal ArticleDOI
Application characteristics of permanent magnet synchronous and brushless DC motors for servo drives
Pragasen Pillay,R. Krishnan +1 more
TL;DR: In this paper, the authors compare the performance of the permanent magnet synchronous motor (PMSM) and the brushless DC motor (BDCM) on the basis of known engineering criteria such as power density, torque per unit current, speed range, feedback devices, inverter rating, cogging torque, ripple torque and parameter sensitivity.
Journal ArticleDOI
Multilevel selective harmonic elimination PWM technique in series-connected voltage inverters
TL;DR: The selective harmonic elimination PWM (SHEPWM) method is systematically applied for the first time to multilevel series-connected voltage source PWM inverters using a phase-shift harmonic suppression approach.
