   Communication Networks For Drive-By-Wire Applications

Abstract: The automotive market is more and more interested in all-electric systems for the execution of the driving commands, i.e. in the so-called Drive-by-Wire (DbW) systems. The most crucial issue in their usage is the achievement of acceptable levels of dependability. From this point of view, the communication network of a DbW system is a critical component. Being the traditional fieldbuses used in the cars not suited to highly dependable applications, new communication networks have been devised, built up around protocols that accommodate powerful techniques to assure the dependability in the data exchange. This paper illustrates the characteristics of the communication networks for DbW systems, focusing on the techniques adopted to stand up against errors and faults of communication.

 
   Comparison Of Induction Motor, Permanent Magnet Motor And Transversal Flux Motor For Wheel Hub Drives In Street Cars 
 By Wilhelm Hackmann, Andreas Binder

 [Download] 
Abstract: A comparison of built prototypes of induction motor, permanent magnet motor and transversal flux motor for wheel hub drives in street cars is presented concerning dimensions, masses, electrical and thermal performance. The induction motor proved to be the best economical solution, whereas the permanent magnet motor may be considered as the drive with highest technical performance. Due to the big stray flux of the transversal flux motor the converter rating of this type of machine was the highest at rated power (35 kW, 240 rpm). The stray flux caused also considerable stray load losses, which decreased efficiency remarkably at high speed. Nevertheless the transversal flux motor has the lowest active mass for rated torque at low speed.

 
   Discrete-Time Field-Oriented Control For SM-PMSM Under Asynchronous And Synchronous PWM Operations 
 By Abdelkrim Benchaib, Jean-Claude Alacoque, Serge Poullain And Jean-Luc Thomas 
 [View] 
 [Download] 
Abstract: This paper deals with surface mounted permanent magnet synchronous motors (SM-PMSM) control under Pulse Width Modulation (PWM) working in asynchronous and synchronous modes. The main objective of such algorithm is to perform flux and torque high dynamics control related to specific railway requirements. Such type of applications necessitate to consider an additional harmonic constraints (harmonic shape) as well as DC Bus voltage limitations. Indeed, generated harmonics could produce electromagnetic interference with signaling systems, and voltage drop in the catenary supply or pantograph jump introduce DC bus fluctuations. Consequently, the PWM will be considered as an entire part of the control objectives taking into account the DC Bus voltage state variation. For both asynchronous and synchronous modulation modes, an unified control laws will be synthesized with corresponding geometric interpretations. Experimental results for a specific railway application test bench will be presented to highlight the control performances of such algorithm.

 
   Modeling Of Influences Affecting A Linear-Drive-System

Abstract: For the systematic model-based optimization of complex mechatronic systems models are required, describing not only the basic function of subsystems, but instead reflecting the influences from one subsystem to another. This paper presents the modeling of influences on a doubly fed long stator linear drive of a railway system, used as demonstrator for selfoptimization methods.

Abstract: The Wounded Rotor Synchronous Machines (WR-SM) is very well known in the salient pole configuration for applications as electrical generator operating at constant speed. In this paper, the use of a WR-SM as motor for the electric traction of heavy electric vehicles is investigated. The main features of the proposed drive system are the capability to generate high torque at very low speed without excessive overload of the stator windings and to operate theoretically at constant power untill unlimited speed. Therefore, the proposed drive system is very well suited to satisfy the torque and speed demands of heavy electric vehicles such as busses, trucks, industrial lift trucks and Light Rail Transit (LRT). The analysis of the control strategy, performed using a space vector approach in the d-q plane, has been firstly developed by means of a linear model of the machine, then it has been extended to non-linear operating conditions. The effectiveness of the proposed drive system has been verified by experimental tests on a laboratory prototype.
