Betriebsinformationssysteme für Energieerzeuger

The competition caused by the liberalization of the energy market forces the operators of transverse compound systems to use all technically possible and economically meaningful rationalization potentials more strongly than so far. Apart from the improvement of the technical processes in the production systems a special meaning comes to the optimal planning of the application of the power stations. Already at small power supply systems an EDP-supported editing of data and information from the enterprise process and the system inventory becomes inevitable due to the complexity and the ever growing information obligations to officials.

Sensorintegration für Industrie-Robotersteuerungen

Robot applications applying external sensors can only be implemented with limitations using an industrial robot controller, or have to make use of a special controller. The presented activities of EMST aim at the development of an open and flexible robot control system suiting well for sensor applications. The main aspect of research is a sensor integration in an industrial control system being able to perform fast and complex interactions with robot movement.     

Computermodelle für Mikrowellenleistungstransistoren

Coming cell phone systems like UMTS or digital audio broadcast (DAB) systems impose high demands on transmitter amplifier linearity. Analytical models of the microwave transistors used in the driver and power amplifier stages are necessary to describe the large signal behavior for design optimization. This paper shows how DC-IV and small signal measurements are used to generate a large signal model of microwave power transistors. Effects that have special influence on transmitter amplifiers will be emphasized.     

Sensorlose INFORM-geregelte Permanentmagnet-Außenläufermotoren für Industrie, Automotive und Traktion

In this paper, the optimization of external rotor permanent magnet motors with respect to sensorless position detection using the INFORM method is presented. The external rotor type offers special advantages in drives with high torque demand, especially at low speed and standstill. Typical applications are elevators, starter-generators and traction drives. Furthermore, the paper shows the calculation of reluctance properties due to saturation and geometry using numerical field calculation. This is an important fact for high-performance position estimation using the INFORM method. The accuracy of position estimation reaches a few electrical degrees; therefore it is fully sufficient for practical application in the mentioned fields. At the Institute of Electrical Drives and Machines at Vienna University of Technology, such PM external rotor drives have been designed, built and tested. The sensorless operation has been verified successfully.
