The paper presents a cascade control scheme for Permanent Magnet Synchronous Motors (PMSMs) based on a novel reduced order state observer which provides accurate speed tracking performance. The asymptotic vanishing of both the observation error and the speed tracking error is proven. The observer design allows a residual signal to be defined, able to detect faults using Park’s vector currents. ...

Power electronics-based converters have been widely used in several applications, specifically electric propulsion systems. Ongoing advancements led to high-gain Quadratic Boost Converters (QBC) which control Permanent Magnet Synchronous Motor (PMSM) drive. In this work, a novel scheme is employed, particularly three-phase inverter between QBC and PMSM operated by dual-mode controller strategy....

With ever increasing oil prices and concerns for the natural environment, there is a fast growing interest in electric vehicles (EVs). However, energy storage is the weak point of the EVs that delays their progress. For this reason, a need arises to build more efficient, light weight, and compact electric propulsion systems, so as to maximize driving range per charge. There are basically two wa...

The conventional Proportional-Integral ...

Recently, interior permanent magnet synchronous motors (Interior-PMSMs) have become known as a good candidate for hybrid electric vehicle (HEV) traction drive application due to their unique merits. However, the dynamic and steady-state behaviors of these motors are quite dependent on the permanent magnet (PM) type, configuration, and volume in rotor structures. This paper uses a novel structur...

An implementation for sinusoidal current control of a slotless Permanent Magnet Synchronous Motor (PMSM) with discrete Hall sensor position feedback is presented. To estimate the rotor position of the slotless PMSM, a flux estimation technique is used that takes advantage of the slotless machine’s characteristically low inductance to limit flux estimation error. The rotor position is estimated ...
