Liviu KREINDLER:
IMPLEMENTATION OF DIGITAL MOTION CONTROLFUNCTIONALITY USING DSP PROCESSORS
Presenters: Kreindler, Liviu
Abstract

The field of Digital Motion Control (DMC) had a significant evolution during the last decade, due to impressive technological advances of digital control, sensors and power electronics components. Accelerated improvement of performances, combined with important price reductions, allowed the transfer of advanced technology solutions from research and laboratory level to the real life industrial field. In this context, DSP controllers dedicated to DMC applications represent an important option in order to control both motor as well as motion functionality, mainly in distributed intelligence configurations. Flexible DMC structures can be implemented using dedicated DSP controllers, up to the level of ?intelligent drives? which handle basic motor control functionality, as well as advanced reference generator, field bus communication protocols and high level motion language programmability.

Gábor Péceli:
RESEARCH AND EDUCATION IN THE FIELD OF EMBEDDED INFORMATION SYSTEMS
Presenters: Péceli, Gábor
Abstract

The scientific and technological novelty of Embedded Information Systems (EISs) is the completely new level of coexistence of computational and physical systems. EISs are autonomous, dependable, ?invisible? computational systems, which intensively exchange information with their physical/chemical/biological environment. The first part of the paper gives an overview of the current research activities related to EISs. The challenging nature of research in the field of EISs is due to the fact that on one hand the science of physical systems does not consider computational limitations, while on the other the science of computations is abstracted away the physical world, thus these two areas represent disjoined disciplines. As a simple consequence educators of research universities rarely offer courses, which systematically combine the two fields. The second part of the paper reports the experiences of a quite recent attempt to teach EISs to electrical and computer engineering students at BME.

Tamás RUZSÁNYI:
ENASCENCE OF ELECTRIC DRIVEN RUBBER-WHEELED VEHICLES IN CITY PUBLIC TRANSPORT
Presenters: None.
Abstract

Today, the majority of passengers travel by combustion engine vehicles and only 1% uses electric transport facilities. This rate is more favourable in case of cities, but it does not influence the fact that basically combustion-engine vehicles are used for public transport because of their lover investment cost, developed infrastructure and their flexibility. After a period of recession in the second half of the 20th century, electrical vehicles play again an increasingly important role in the city public transport. Several factors contribute to this situation, like: air pollution problems in the metropolitan areas, the expectable drastic increase in the price of oil-based fuels, the new developments for higher passenger and driver comfort, as well as, the improvement in the flexibility of vehicles. There are new electric public transport lines under construction in many big cities. The paper presents the new generation of trolleybuses.
