The widely used converter models in most of the power electronics and power system applications are the DC-DC converter models. Increase in switching losses has been observed in Conventional Diode Bridge Rectifier (DBR) and hence the researchers are more focused towards bridgeless converters. The design of a novel bridgeless cuk converter model with buck mode operation is focused in this work. ...

This paper proposes a high-precision intelligent adaptive backstepping control system (HPIABCS) for the position control of permanent-magnet synchronous motor (PMSM) servo drive. The HPIABCS incorporates an ideal backstepping controller, a dynamic recurrent-fuzzy-wavelet-neural-network (DRFWNN) uncertainty observer and a robust H∞ controller. First, a backstepping position controller is designe...

The principal aim of this paper is a study and improves of sensorless vector control (VC) of a permanent magnet synchronous motor (PMSM). We interested mainly of the Luemberger observer. This method is based on a representation of the state of the dynamic model of the motor. In order to optimize the performance of the drive system, the genetic algorithm is proposed as an intelligent technique a...

A new collaborative design scheme of a super-high-speed permanent-magnet synchronous motor (PMSM) and its digital controller is presented, which provides a low-cost but highly efficient motor system with guaranteed stability and performance. Since the systematic design of the PMSM can ensure its stability over the full operating speed range, a simple and reliable open-loop controller can be des...

Stator turn faults in permanent magnet synchronous motors (PMSMs) are more dangerous than those in induction motors (IMs) because of the presence of spinning rotor magnets that can be turned off at will. Condition monitoring and fault detection and diagnosis of the PMSM have been receiving a growing amount of attention among scientists and engineers in the past few years. The aim of this study ...

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...

In the present work, an integrated method of pole shape design optimization for reduction of torque pulsation components in permanent magnet synchronous motors is developed. A progressive design process is presented to find feasible optimal shapes. This method is applied on the pole shape optimization of two prototype permanent magnet synchronous motors, i.e., 4-poles/6-slots and 4-poles-12slots.

The four-wheel-drive electric vehicle's traction chain is powered by four permanent-magnet synchronous motors (PMSM), a single three-phase, five-leg inverter (FLI). In order to achieve the behavior of mechanical differential and require parallel wheel-motors turn at identical or different speeds, using this structure, an independent control applied on each driving wheel. For particular there sh...

This paper proposes a loss minimization control method based on improved gradient descent algorithm (GDA) for interior permanent magnet synchronous machine (IPMSM). Since the power of PMSM is derived from measured phase voltage and current, this independent iron model containing motor parameters. Meanwhile, it can guarantee stability system when entering searching period. Both maximum torque pe...

Today the interest for Hybrid electric vehicles (HEV) is high due to their ability to reduce the fuel consumption, which means a reduction in the operation cost as well as in the environmental impact. Weight and volume is important and the machine type with smallest size for a given performance is usually the permanently magnetized synchronous machine (PMSM). To be able to control the PMSM with...
