![]() | Communication Networks For Drive-By-Wire Applications
By Manuele Bertoluzzo, Giuseppe Buja, Alberto Zuccollo | |
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 | |
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 | |
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
By B. Schulz, A. Pottharst, N. Froehleke, J. Boecker | |
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.

![]() | Wounded Rotor Salient Pole Synchronous Machine Drive For The Traction System Of Electric Vehicles
By D. Casadei, C. Rossi, L. Zarri, A. Pilati, A. Gaetani | |
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.
