2. 1. On Modeling and Control of Flexible Manipulators

   Author : Stig Moberg; Svante Gunnarsson; Anders Robertsson; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; multivariable systems; differential-algebraic equations; robots; manipulators; flexible structures; robustness; position control; nonlinear systems; closed-loop identification; frequency-response methods; industrial robots; robotics; control; feedforward; flexible arms; Automatic control; Reglerteknik;

   Abstract : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and quality. Other reasons for using industrial robots are cost saving, and elimination of heavy and health-hazardous work. READ MORE

4. 2. Aeroelastic Concepts for Flexible Wing Structures

   Author : Sebastian Heinze; Ulf Ringertz; Bengt Winzell; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active aeroelasticity; flexible wings; aeroelastic control; design; experiments; testing; analysis; robust; uncertainty; Engineering mechanics; Teknisk mekanik;

   Abstract : This thesis summarizes investigations performed within design, analysis and experimental evaluation of flexible aircraft structures. Not only the problems, but rather the opportunities related to aeroelasticity are discussed. READ MORE

5. 3. Aeroelastic Concepts for Flexible Aircraft Structures

   Author : Sebastian Heinze; Dan Borglund; Rick Lind; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeroelasticity; active aeroelastic aircraft structures; aeroelastic control; wind-tunnel testing; flutter analysis; robust flutter analysis; worst-case configuration; Vehicle engineering; Farkostteknik;

   Abstract : In this thesis, aeroelastic concepts for increased aircraft performance are developed and evaluated. Active aeroelastic concepts are in focus as well as robust analysis concepts aiming at efficient analysis using numerical models with uncertain or varying model parameters. READ MORE

6. 4. Design and Testing of Flexible Aircraft Structures

   Author : Martin Carlsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeroelasticity; active aeroelastic structures; aeroelastic tailoring; control; structural optimization; wind-tunnel testing;

   Abstract : Methods for structural design, control, and testing offlexible aircraft structures are considered. Focus is onnonconventional aircraft con- figurations and control concepts.The interaction between analysis and testing is a central topicand all studies include validation testing and comparisonbetween computational and experimental results.

7. 5. EFFICIENCY OF FLEXIBLE FIXTURES: DESIGN AND CONTROL

   Author : Ilker Erdem; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; control; design; fixture; assembly; manufacturing; efficiency; flexible; production;

   Abstract : The manufacturing industries have been using flexible production technologies to meet the demand for customisation. As a part of production, fixtures have remained limited to dedicated technologies, even though numerous flexible fixtures have been studied and proposed by both academia and industry. READ MORE
