Despite two decades of massive strides in research and development on control strategies
and their subsequent implementation, most books on permanent magnet motor drives still …

For permanent-magnet synchronous machines (PMSMs) sensorless control, the widely
employed high-frequency (HF) pulsating carrier signal injection method is based on tracking …

A nonlinear observer for surface-mount permanent-magnet synchronous motors (SPMSMs)
was recently proposed by Ortega et al.(LSS, Gif-sur-Yvette Cedex, France, LSS Internal …

This paper deals with a novel approach for the real-time tracking of the maximum-torque-per-
ampere (MTPA) trajectory of an interior permanent-magnet (IPM) motor drive. The proposed …

The synchronous reluctance machines with transversally laminated rotor and multi flux
barriers per pole reach a high torque density, so that they are proposed as a valid alternative …

Direct torque control of interior permanent-magnet synchronous motors is known to deliver
fast torque and flux dynamic responses. However, the poor flux estimation at very low …

This paper investigates the effectiveness of sensorless operation in carrier-signal-injection-
based sensorless-control methods for permanent-magnet brushless ac motors. The …

Sensorless machine drives in vehicle traction frequently experience rapidly-changing load
disturbance and demand fast speed dynamics. Without gain-scheduling or compensation …
