Closed-loop Identification of Multivariable Systems: With or Without Excitation of All References?

Dominique Bonvin, Alireza Karimi, Ljubisa Miskovic

A variance analysis of the parameters of a plant, belonging to a class of multivariable systems, estimated in closed-loop operation is performed. More specifically, having in mind the control applications where it is not desirable to excite all external re ...

SwissCube Inertia Wheel Assembly - Electronics

Omar Scaglione

The Inertia Wheel Assembly (IWA) is composed by the IWA motor, the inertia wheel and the command electronics. IWA belongs to the Attitude Determination and Control System (ADCS) of the SwissCube satellite. Swisscube is a pico-satellite that complies with C ...

Fifty years of self-assembly experimentation

Roderich Gross

In this paper, we review half a century of research on the design of systems displaying (physical) self-assembly of macroscopic components. We report on the experience gained in the study of 22 such systems, exhibiting components ranging from passive mecha ...

In vitro breeding of Brassica juncea L. to enhance metal accumulation and extraction properties

Jean-Paul Schwitzguebel, Erika Nehnevajova

In vitro breeding and somaclonal variation were used as tools to improve the potential of Indian mustard (Brassica juncea L.) to extract and accumulate toxic metals. Calli from B. juncea were cultivated on a modified MS medium supplemented with 10–200 μM C ...

Intrinsic, thermal and hygroscopic residual stresses in thin gas-barrier films on polymer substrates

Yves Leterrier, Grégory Tornare

Intrinsic, thermal, and hygroscopic contributions to the in-plane residual stress in silicon nitride films on polyimide substrates are identified, based on iso- hygric thermal ramps and isothermal relative humidity jumps, combined with non-linear elastic m ...

A Promising Technique to Increase Metal Concentration and Extraction in Sunflowers

Jean-Paul Schwitzguebel, Erika Nehnevajova

Since most of the metal-hyperaccumulating wild plants only produce very low biomass and many high-yielding crops accumulate only moderate amounts of metals, the current research is mainly focused on overcoming these limitations and the optimization of meta ...

Controllability and Stability of Repetitive Batch Processes

Dominique Bonvin

Batch control has traditionally addressed the problems related to the absence of a steady state and the finite batch duration. Recently, batch control has added the dimension that arises naturally from the possibility of applying run-to-run control, i.e. i ...

Turbine Speed Governor Parameters Validation in Islanded Production

François Avellan, Jean-Jacques Simond, Christophe Nicolet, Philippe Allenbach, Basile Kawkabani, Bob Greiveldinger

The transient behavior of hydroelectric power plants is of high interest for ensuring stability of islanded electrical power networks. Therefore, it is suitable to determine and validate the set of parameters of a turbine speed governor using a realistic s ...

Novel cantilever design with high control of the mechanical performance

Luis Guillermo Villanueva Torrijo

A novel mechanical structure design with reduced deflection offset is reported. This design offers a batch processing solution to a well-known problem in the fabrication of very thin crystalline silicon structures, that is initial bending due to anchoring ...

Self-Organised Coordinated Motion in Groups of Physically Connected Robots

Francesco Mondada, Mirco Dorigo, Michael Bonani

An important goal of collective robotics is the design of control systems that allow groups of robots to accomplish common tasks by coordinating without centralized control. In this paper, we study how a group of physically assembled robots can display coh ...
