This article investigates maximum possible torque improvement in a two-pole surface permanent magnet synchronous machine with reduced span, which causes production of highly nonsinusoidal back electromotive force (EMF). It contains high third and fifth harmonics, can be used for the enhancement, using stator current harmonic injection. Optimal span is studied first, it shown that such value, wo...

Due to the particularity of synchronous reluctance motor (SynRM) structure, a novel high-performance model predictive torque control (MPTC) method was proposed reduce high ripple and improve performance efficiency motor. First, precise parameters SynRM reflecting magnetic saturation characteristics were calculated using finite element analysis (FEA) data, flux linkage maximum per ampere (MTPA) ...

Electric vehicles (EVs) integrate two main power electronics systems, namely, the battery charging system and traction system. In this study, we aimed to complement deepen study of latter, more specifically, focusing on a based synchronous reluctance permanent magnet (SRPM) machine, since is an emerging electric machine in EV paradigm. The developed prototype integrates bidirectional ac-dc dc-d...

For the permanent magnet synchronous wind generator, a control method based on losses minimization is proposed, in order to solve problem of maximum energy tracking control, which often neglects generator caused by deviation between actual working point and optimal power point, leads output loss. Then, considering loss small-signal used establish transfer functions main components, such as turb...

Objectives: This paper simulates a high-performance PI and FLC-based controller for an IPMSM drive in which the speed should closely follow reference voltage-current trajectory with different conditions like load disturbance, variation circuit parameters, control strategy. In FOC, fuzzy are used sliding mode control. generates d-axis current (Id) q-axis (Iq), torque magnetic field vector each s...

This paper presents an on-line fuzzy tuning scheme for indirect field-orientation (IFO)-controlled induction machine drives. A fuzzy controller is used to regulate the speed, and another two fuzzy compensators are combined to correct detuning of field orientation. Since detuning effects of the IFO induction machine drive is minimized by the new fuzzy control scheme, the induction machine can ac...

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...

This paper offers a novel dual-mode double stator wound rotor synchronous machine for variable speed applications. The proposed motor integrates the benefits of both traditional (WRSM) and brushless (BL-WRSM). A constant torque can be attained in maximum per ampere region by operating as WRSM Mode I, power field-weakening it BL-WRSM II. Moreover, due to dual-stator structure, exhibits improved ...

An improved vector control method is presented in this study to enhance synchronous reluctance motor (SynRM) performance. The maximum torque per ampere (MTPA) technique has demonstrated good dynamic properties since the closely tied current control. selection of approach primarily influenced by how reference values will be defined.

Interior permanent-magnet synchronous machines are widely spreading in automotive and vehicle traction applications, because of their high efficiency over a wide speed range. This capability can be achieved by appropriated control strategies: Maximum Torque per Ampere (MTPA), Flux Weakening (FW) Volt (MTPV). However, these trajectories often based on an simplified magnetic model the electrical ...
