Microfrabricated Mirrors For Space Applications

Nico de Rooij, Caglar Ataman, Wilfried Noell, Sébastien Lani, Dara Zaman Bayat, Benedikt Guldimann

We report on the advances towards the design and fabrication of a system consisting or two 10mm mirrors, one actuated magnetically and the other electrostatically. The system will be used for beam steering. The maximum resonant frequencies and deflection a ...

Design for Self-Sensing of a Linear Actuator

Yves Perriard, Miroslav Markovic, Joël Maridor

This paper presents a complete method for optimizing a linear actuator in order to perform its sensorless speed control. The optimizer maximizes the difference of inductances between two positions of interest in order to perform the efficient position dete ...

Deployment of a Pentagonal Hollow-Rope Tensegrity Module

Ian Smith, Landolf-Giosef-Anastasios Rhode-Barbarigos, Nizar Bel Hadj Ali, René Motro

Tensegrity structures are spatial reticulated structures composed of cables and struts. Tensegrity systems are good candidates for adaptive and deployable structures and thus have applications in various engineering fields. A “hollow-rope” tensegrity syste ...

Escola a Manresa / School in Manresa

Sergi Aguacil Moreno

The project is developed around a central courtyard in response to the site where it is located, while taking advantage of the existing slope to resolve the position of the singular buildings in relation to the system of grouping classrooms; the direct con ...

Sensorless Position Detection of a Linear Actuator

Nikola Katic

The goal of the project is to explore the possibility of controlling the speed of the actuator’s moving part without using any sensor. The speed has to be set accordingly to the position of the moving part at specific time. This dependency is fixed and is ...

DMCMN: In Depth Characterization and Control of AFM Cantilevers With Integrated Sensing and Actuation

Georg Fantner

New developments in MEMS (microelectromechanical systems) fabrication allowed the development of new types of atomic force microscopy (AFM) sensor with integrated readout circuit and actuator built in on the cantilever. Such a fully instrumented cantilever ...

Optimization design of a linear actuator using a genetic algorithm

Yves Perriard, Miroslav Markovic, Joël Maridor

This paper presents a method to optimize two linear actuator configurations. The method is stochastic and combines a genetic algorithm (GA) and FEM (finite element method) model generated with the commercial software FEMM. The optimization is performed in ...

Towards Self-sensed Drives in Linear Haptic Systems

Yves Perriard, Grégory Savioz

Within the framework of a project consisting in developing a novel haptic computer keyboard, force and position control is required for each key. The previous project phase consisted in the design and optimization of a miniature actuator which is to be ins ...

Sensorless position detection of a linear actuator using the resonance frequency

Yves Perriard, Nikola Katic, Joël Maridor

This paper presents a method to detect the position of a linear actuator without any position sensor. The actuator winding has a resonance frequency that is very related to the position of the linear actuator moving part. A sinusoidal scan voltage is super ...
