The paper presents results of studies on the sensorless drive with permanent magnet synchronous motor (PMSM) supplied through the motor choke. The position is estimated using a modified Luenberger observer. Its modification consists in using a PII correction function instead a proportional one, which gives smaller estimation errors. The advantages of that observer structure are simple structure...

The main theme of this paper is to present novel controller, which is a genetic based fuzzy Logic controller, for interior permanent magnet synchronous motor drives with direct torque control. A radial basis function network has been used for online tuning of the genetic based fuzzy logic controller. Initially different operating conditions are obtained based on motor dynamics incorporating...

This paper presents a strategy for vector control of Permanent Magnet Synchronous Motor (PMSM) drive fed with a diode clamped multilevel inverter. In the proposed work the conventional 2-level inverter is replaced with three and five level inverters in PMSM drive system. The implementation of multilevel inverters improved the torque and speed response under various operating conditions. PI cont...

Because the output signal of time grid sensor is so weak and easily affected by disturbing noise, it difficult to extract induction containing position information, when used detect rotor permanent magnet synchronous motor (PMSM). In this paper, an adaptive monostable stochastic resonance method proposed realize detection sensor. The tunnel magnetoresistance effect (TMR) adopted change magnetic...

This paper deals with the modeling, analysis, design and simulation of a robust control method for a permanent magnet synchronous machine (PMSM) supplied with a PWM inverter based on a LPV (Linear Parameter Variation)  standard controller. Under the influence of uncertainties and external disturbances, by a variation of ±150% of motor parameters from the nominal values, the robust performance c...

The magnetic geared permanent magnet synchronous motor (MG-PMSM) is a PMSM that has two rotors with different rotation speeds and includes the function of gear. design studies 45kW-class MG-PMSM are conducted for application driving system tram.

The relationship of permanent magnetic material characteristic parameters was analyzed, and a simulation method of a permanent magnet synchronous motor (PMSM) rotor demagnetization fault was put forward. Based on this, a simulation model of the PMSM under partial demagnetization and uniform demagnetization fault were established, and different degrees demagnetization fault was simulated. Relati...

The traditional radial flux PMSM and axial have an effective air gap on only one side, between the stator rotor, generates electromagnetic torque. There are defects in magnetic-field utilization, it is difficult to improve torque density. Therefore, this paper proposes axial–radial-flux permanent-magnet synchronous motor (ARF-PMSM), which combines with flux, be used elevator-traction machine-dr...

Energy efficiency is an essential aspect of motor technologies. The replacement conventional Single Phase Induction Motor (SPIM) by Permanent Magnet Synchronous (PMSM), Reluctance (SynRM), or Switched (SRM) for energy-efficient operation leads to high capital expenses. This paper presents a cost-effective design method improve the existing SPIM. It implements novel idea transforming it Line Sta...

The position sensorless permanent magnet synchronous motor (PMSM), with its simple structure, is applied in the aerospace field high reliability requirements. To drive PMSM safely, three-phase current measured from driver needs to be isolated for closed-loop control. And then, accuracy measurement crucial achieving optimal performance.
