Parameter identification of PMSM

2016 Progress in Electromagnetic Research Symposium (PIERS), 2016
The following paper describes an identification of quadrature inductances of a permanent magnet synchronous motor. This identification is a frequency analysis base on an injection of a harmonic signal to control. This method utilizes knowledge of synchronous motor schema in d-q coordinates and it is based on mutual signals correlation.

Observability analysis of PMSM

2009 3rd International Conference on Signals, Circuits and Systems (SCS), 2009
The current problems to successfully apply sensorless control techniques for Permanent Magnet Synchronous Motor (PMSM) are the existence of operating conditions for which the observer performance is remarkably deteriorated. This is due to difficulties in estimating correctly the rotor position at low speed.

Maschinendesign für geberlos geregelte PMSM

e & i Elektrotechnik und Informationstechnik, 2017
Die geberlose Regelung permanentmagneterregter Synchronmaschinen ermoglicht eine Reduktion des Bauvolumens und der Gesamtkosten, weil der mechanische Lagegeber entfallen kann. Anisotropiebasierte Verfahren der geberlosen Rotorlageschatzung, die im unteren Drehzahlbereich und im Stillstand verwendet werden, stellen dabei besondere Anforderungen an die ...

Parametric Identification of PMSM Mathematical Model

2019 24th International Conference on Methods and Models in Automation and Robotics (MMAR), 2019
The problems of mathematical modelling and parameter identification of PMSM (Permanent Magnet Synchronous Motor) mathematical model were analysed. The numerical Box's method of static optimisation was applied in offline parametric identification. Parameters of the mathematical models were determined according to minimisation of the mean-square error of

Accurate Torque Ripple Measurement for PMSM

IEEE Transactions on Instrumentation and Measurement, 2011
Torque ripple in permanent-magnet synchronous motors is generally undesirable. Significant work has been done to minimize this torque, either by modifying the mechanical motor design or by careful controller design. Surprisingly, however, little work has been published on the accuracy of torque ripple measurement.

A sensorless passivity-based control for PMSM

2018 International Conference on Electronics, Communications and Computers (CONIELECOMP), 2018
This paper presents a sensorless controller design to speed tracking problem for a Permanent Magnet Synchronous Motor (PMSM). The technique of passivity requires knowing the load torque, this is estimated with a reduced-order extended state observer, a traditional reduced-order observer and an online algebraic estimator.

Direct Tuning Strategy for PMSM Drives

2008 IEEE Industry Applications Society Annual Meeting, 2008
This paper deals with a numerical method for Proportional Integral (PI) controllers design for Permanent Magnets Synchronous Motor (PMSM) drives. The design procedure is based on the manipulation of the system transfer functions to achieve a closed form representation for the parameters of the speed, torque and flux PI controllers.

Measurement-based nonlinear modeling of PMSMs

IECON 2015 - 41st Annual Conference of the IEEE Industrial Electronics Society, 2015
This article is about measurement-based modeling of PMSMs. Typically, these machine designs feature nonlinear characteristics regarding the stator phase currents and show rotor angle dependent behavior. Thus, non-sinusoidal linked fluxes as well as higher torque harmonics occur.

General Formulation of PMSMs

2018
As an energy-converting system, a permanent magnet spherical motor (PMSM) can be characterized as a combination of two subsystems; an electromagnetic system and a rotor dynamic system. The analytical models presented here include the equations governing the magnetic field, energy and force/torque of a PMSM, and the equations of motion describing the ...

Comparison of Radial Flux PMSM and Axial Flux PMSM for Hybrid Electric Tracked Vehicles

2021
Permanent magnet synchronous motors are increasingly becoming predominant with the upscale competitiveness of high-power permanent magnets. Permanent magnets are comparatively more efficient because the field excitation losses are extinguished that leads to significant rotor loss minimization. Thus, the motor efficiency is greatly surpassed, and higher
