The paper is devoted to the synthesis and performance analysis of a direct torque control (DTC) strategy, based on the bus-clamping technique, dedicated to three level NPC inverter fed induction motor drives. The principle of the proposed strategy consists in keeping the voltage vector of each motor phase during 60° of the half of a cycle of the reference stator flux vector. The synthesis of the vector selection tables (one for clockwise rotation and the other for anti-clockwise rotation) is achieved on the basis that enables the fulfilment of the control combinations related to the variations of the stator flux and the electromagnetic torque, along with a reduction of their ripples. Simulation results highlight the torque high dynamic as well as reduced ripple, exhibited by the three level NPC inverter fed induction motor drive under the control of the proposed bus-clamping DTC strategy.

The performance of power lines as a medium to transfer data using advanced technologies needs to be investigated and hence a power line channel modeling is required. In this paper, an effort is made to simulate and model a broadband over power line communication channel to investigate and compare the channel model gain and phase profiles over a frequency range of 0-20 MHz with different and moderate path numbers, differing path parameters and varying line lengths. The results observed from the performance profiles of the work indicate suitability and possibility of transmission over the power line channels. The attenuation is however high under certain conditions.

The paper is devoted to the modeling of a hybrid-excited claw pole alternator (HECPA) by means of a variable position 3D magnetic equivalent circuit (MEC). The study is initiated by the derivation of a MEC with the rotor position kept at the maximum flux linkage between the rotor and stator, enabling the investigation of the steady-state features. The incorporation of the rotor position in the MEC is then considered. A dedicated numerical procedure based on the Newton-Raphson algorithm is developed for the resolution of the proposed variable position MEC. The obtained fluxes, for the different considered positions, allow the prediction of the HECPA time-varying features under no-load operation. A comparison between the results predicted by the variable position MEC and those computed by finite element analysis reveals a good agreement.

This paper applies the novel partitioned stator (PS) permanent magnet (PM) (PSPM) machines to hybrid and electric vehicle (HEV/EV) applications. A globally optimized PSPM machine having the same overall dimensions as the Prius2010 interior-PM (IPM) machine is presented. It shows that the PSPM machine can exhibit larger torque density, better flux-weakening capability, as well as higher efficiency. Furthermore, a globally optimized PSPM machine employing the same PM usage volume as the Prius2010 IPM machine is also obtained. It can exhibit comparable torque density as the Prius2010 IPM machine, higher torque at light load, and also a wider constant power operation range as well as higher efficiency.

This paper evaluates the performance of synchronous reluctance machine (SynRM) and permanent magnet assisted synchronous reluctance machine (PMASynRM) for low-cost ventilation application. A unified mathematical model is established with interior permanent magnet synchronous machine (IPMSM) for comparison. Besides, permeability frozen method is utilized to distinguish basic electromagnetic torque and reluctance torque. Both efficiency and power factor at whole speed region are assessed to demonstrate the optimal working region of the three analyzed machines.

Power lines at distribution level can represent an attractive medium for broadband delivery. They reach more homes than coaxial cable systems or telephone lines and hence broadband can be delivered everywhere where these lines reach. This paper presents characterization of power line channel for digital data transfer over low voltage distribution lines system. The work is based on the power line characterization using scattering matrix approach. It is demonstrated that varying network topologies of indoor power line channel can be modelled using two-port network theory for accurate results. The comparison of transfer function is obtained for two wire and coaxial cabling techniques. The simulations are performed to observe and reveal that the characteristics of channel depend on frequency, termination type, and cable type. The authors also make an effort in the direction of designing and simulating a typical coupling circuit under different load conditions.

From directional surveys, calculating the well courses can generate errors due to the uncertainty of the survey methods. These methods are analyzed and discussed in terms of which of these models approximates the real well course best, since all models yield different results with the same given survey data. This paper studies a real case of directional well design, which was obtained from Al-Kafji Joint Operation Company (KJOC) with the resulting data of the well path. Two common directional drilling survey methods are applied on the real case and the results have been compared and discussed.

The aim of this paper is to apply a hybrid analytical method (HAM) for the thermal modelling of tubular linear machines. This technique has been successfully applied for the electromagnetic modelling of electrical machines and it gives relatively good results as compared to finite element method (FEM). The HAM is based on the coupling of a macro-element, based on the analytical solution of heat equation, for the mechanical air-gap with a mesh based generated lumped parameter thermal model for the rest of the studied structure. In order to validate the proposed modelling approach, results issued for the HAM are compared to corresponding results obtained from a FE analysis. This modelling approach should constitute a useful tool for the pre-design of electrical machines.

This computational simulation study presents an innovative approach for structural damage detection in “smart” civil infrastructure systems. The proposed approach is predicated upon the utilization of the compressed data stored in memory chips of a newly developed self-powered wireless sensor. An efficient data interpretation system, integrating aspects of the finite element method (FEM) and probabilistic neural networks (PNN) based on Bayesian decision theory, is developed for damage detection. Several features extracted from the cumulative limited static strain data are used as damage indicator variables. The efficiency of the method is tested and evaluated for the complicated case of a bridge gusset plate. The gusset plate structure is analysed via 3D FE models. A general scheme is presented for finding the optimal number of data acquisition points (sensors) on the structure and the associated optimal locations, taking into account the influence of sensor sparsity and the level of data corruption due to noise.

Aerospace development needs an optimum in weight and volume reduction. In addition there is a high research potential on vehicle energy concepts and alternative energy converters by using synergies from aerospace research [1]. The understanding of the system behavior leads to the development of several concepts of electric drives which combine more than one function in a single technical component. The paper describes three examples of highly integrated electric drive concepts which can be used in next generation cars. The concepts are partly based on international cooperation and also on individual investigation work.
