   A Study Of The Space Mapping Approach To The Inverse Design Problem Of A Coreless Actuator
By L. Encica, E. A. Lomonova, A. J. A. Vandenput [View]
[Download]

Abstract: The traditional approach for solving inverse design problems involves an optimization procedure applied to an accurate numerical model (e.g. a finite element model) with high computational requirements. The space mapping technique provides the possibility of a significant reduction in the number of simulations of the accurate model by employing a second model, characterized by lower accuracy and low computational requirements. A coreless electromagnetic actuator is selected as a study model. The same inverse problem is solved with a classical optimization procedure (Nelder-Meade Simplex) and the simulation time of the two algorithms is compared.

   Control Problems Of Oscillating Synchronous Motor
By Sigitas Kudarauskas, Eleonora Guseinoviene, Loreta Simanyniene, J. Vaupsas, Audrius Senulis [View]
[Download]

Abstract: In this paper the control problems of oscillating synchronous motor in the piston compressor drive are studied. The control of oscillation amplitude and centre is investigated. The results of modelling and simulation show that it is possible to accomplish sensorless control of the mentioned values.

   Integrating Switch Mode Audio Power Amplifiers And Electro Dynamic Loudspeakers For A Higher Power Efficiency
By Soren Poulsen, Michael A. E. Andersen [View]
[Download]

Abstract: The work presented in this paper is related to integration of switch mode audio amplifiers and electro dynamic loudspeakers, using the speaker's voice coil as output filter, and the magnetic structure as heatsink for the amplifier.

   Shape Memory Alloys - Actuator For Using In Movable Tactile-Graphical Device For Visually Impaired People
By R. Graf [View]
[Download]

Abstract: Tactile-graphical devices (tactile displays) are used for presentations of graphics to visually impaired persons. The patented tactile display consists of plurality of independently controllable actuator elements that are able to exert forces to the user's finger surface. In this work we present a graph-analytical method to check the time of setting and resetting of shape memory alloy (SMA) wire for applications as actuators in tactile displays to visually impaired people. Calculation results are compared with experimental data. Analysis results can be used to construct a natural display model. Such a model has advantages in reliability, costs and simplicity, compared to known analogues models. It is a step to bring shape memory actuators closer to the market. It allows fabrication of high resolution tactile Braille displays by using advantages of SMA wires.

   Towards The Control Of Chaos In A Step Motor
By B. Robert, F. Alin, M. Feki, C. Goeldel [View]
[Download]

Abstract: We start with a short recall on the modelling of the step by step motor (stepper). This model allows checking by simulation the existence, under certain conditions, of chaotic behaviours in this electromechanical converter. These results are further validated by experimental results. Then, we show the experimental device and its characteristics. Finally the last part presents various possible strategies for the control of chaos in the stepper as well as an experimental tool for rapid prototyping which allows the validation of various studied algorithms.
