Observability analysis of PMSM
2009 3rd International Conference on Signals, Circuits and Systems (SCS), 2009The 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.

Performance Comparison Between an Amorphous Metal PMSM and a Silicon Steel PMSM
IEEE Transactions on Magnetics, 2019Two types of surface-mounted permanent magnet synchronous machines (PMSMs) with the same physical dimensions but different stator core materials are comparatively analyzed, prototyped, and tested in this paper. In order to quantify the magnetization and loss characteristics of the stacked amorphous metal (AM) stator core, an experiment is conducted ...

Experimental research at traction PMSMs
Proceedings of 21st International Conference Radioelektronika 2011, 2011The paper deals with the significant results of the experimental research of the harmonic spectrum of currents and induced voltages at traction permanent magnet synchronous motor (PMSM). The experiments were done in a special workplace with a real traction drive for wheel vehicles. The current harmonic spectrums were analyzed by a specialized device on

VHFIM sensorless control of PMSM
2010 IEEE International Symposium on Industrial Electronics, 2010The paper deals with combined real-time model of PM synchronous motor for sensorless position control. Real-parametric-and real-time model could be ideal tools for both control and simulation of the PMSM position drive. Unfortunately that idealized model doesn't exist so far.

Identification of PMSM nonlinear part
IFAC Proceedings Volumes, 2013Abstract This paper describes the identification of permanent magnet synchronous motor through Hammerstein model. Motor is divided into two systems: a static nonlinear part and dynamic linear part. The only static nonlinear part is used for identification of quadrature and direct inductance by numeric methods namely Newton method and Gauss-Newton ...

2010 12th International Conference on Optimization of Electrical and Electronic Equipment, 2010
With increasing performance of magnet material and decreasing cost permanent magnet synchronous machines (PMSM) become more and more important for practical use in light railway and e-car applications. Excellent torque dynamics are extremely important in these applications - not because of acceleration or deceleration, but to meet additional demands as

2010 International Symposium on Computer, Communication, Control and Automation (3CA), 2010
Based on Lyapounov stability theorem, an adaptive controller is proposed for speed tracking control of permanent magnet synchronous motor (PMSM). The design of the adaptive gain is used to tackle the disturbance. The simulation results show that the design scheme of the PMSM is robust against perturbation and the asymptotical stability of the speed ...

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 ...

Pseudo Sensorless Control of PMSM
2006 12th International Power Electronics and Motion Control Conference, 2006Pseudo sensorless permanent magnet synchronous motor torque and flux tracking control algorithm is presented. Proposed approach addresses the problem of operation at zero, low and up to nominal speed. The information of flux is extracted using a nonlinear closed loop rotor flux observer combined with the information obtained from hall sensors, which ...

Online Switching Strategy Between Dual Three-Phase PMSM and Open-Winding PMSM
IEEE Transactions on Transportation ElectrificationTo make full use of the advantages of dual three-phase permanent magnet synchronous motor (DTP-PMSM) and three-phase open-winding permanent magnet synchronous motor (OW-PMSM), this article proposed a novel typology of the motor drive which can switch between dual three-phase (DTP) structure and three-phase open-winding (OW) structure online.
