This paper proposes a novel extended electromotive force (EEMF) observer of dual three-phase permanent magnet synchronous motor (DTP-PMSM) operable to the position sensorless overmodulation drive. The drive occurs in current harmonics, and estimated EEMF also contains harmonic components, leading ripple error position. Based on vector space decomposition (VSD) utilized DTP-PMSM control, propose...

An adaptive fuzzy control method is developed to control chaos in the permanent magnet synchronous motor drive system via backstepping. Fuzzy logic systems are used to approximate unknown nonlinearities, and an adaptive backstepping technique is employed to construct controllers. The proposed controller can suppress the chaos of PMSM and track the reference signal successfully. The simulation r...

The direct torque controlled (DTC) permanent magnet synchronous motor (PMSM) has become attractive because of its simplicity and fast torque response. However, mechanical sensors have caused problems to the system. It is possible to overcome the disadvantage if the initial rotor position is known. For the initial rotor position detection, the structural and magnetic saturation saliencies are fr...

A New Adaptive Self-Tuning Fourier Coefficients Algorithm for Periodic Torque Ripple Minimization in Permanent Magnet Synchronous Motors (PMSM) Torque ripple occurs in Permanent Magnet Synchronous Motors (PMSMs) due to the non-sinusoidal flux density distribution around the air-gap and variable magnetic reluctance of the air-gap due to the stator slots distribution. These torque ripples change ...

Permanent Magnet Synchronous Motor (PMSM) drives are widely used in applications where smooth torque is required. However, the main disadvantage of PMSM is torque ripple that leads to mechanical vibration and acoustic noise. For applications that require precise tracking, the machine should be free of torque ripples. Vector controlled PMSM drive provides better dynamic response and lesser torqu...

Cable winch is a crucial component of the shore power system, and Permanent Magnet Synchronous Motor (PMSM) with high efficiency and good maintainability is always used as the drive motor for ship cable winch. In order to deal with the various and complex ocean environment, it is rather important for cable winches to keep the tension constant when picking and laying cables so as to realize cons...

Vector control techniques have made possible the application of PMSM motors for high performance applications where traditionally only dc drives were applied. The vector control scheme enables the control of the PMSM in the same way as a separately excited DC motor operated with a current-regulated armature supply where then the torque is proportional to the product of armature current and the ...
