  1. 1. Active control of vibration and analysis of dynamic properties concerning machine tools

    Author : Henrik Åkesson; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ENGINEERING AND TECHNOLOGY; Active Control; Modal Analysis; Analog Controller;

    Abstract : Vibration in internal turning is a problem in the manufacturing industry. Vibrations appear under the excitation applied by the material deformation process during the machining of a workpiece. READ MORE

  2. 2. Embedded Measurement Systems

    Author : Lars Bengtsson; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Keywords : NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Microcontroller; measurement system; direct sensor-to-controller; time-to-digital converter; phase detector; lock-in amplifier;

    Abstract : The subject of Embedded Measurement Systems (EMS) is the merging of embedded systems and electrical measurement systems. This indicates that EMSs are hardware-software systems dedicated to measuring one or a few physical quantities. READ MORE

  3. 3. On Scalable H-infinity Control

    Author : Carolina Lidström; Institutionen för reglerteknik; []
    Keywords : ;

    Abstract : Many of the classical approaches to controller synthesis do not scale well for large and complex systems. This is mainly due to computational complexity and the lack of distributed structure in the resulting controllers. READ MORE

  4. 4. Analysis of Structural Dynamic Properties and Active Vibration Control Concerning Machine Tools and a Turbine Application

    Author : Henrik Åkesson; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Structural dynamics; Nonlinearities; Turning; Milling;

    Abstract : Vibration in metal cutting is a common problem in the manufacturing industry, especially when long and slender tool holders or boring bars are involved in the manufacturing process. Vibration has a detrimental effect on machining. In particular the surface finish is likely to suffer, but tool life is also most likely to be reduced. READ MORE

  5. 5. Feedback control of resistive wall modes in the reversed field pinch

    Author : Dimitry Yadikin; KTH; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; Physics; Reversed eld pinch; current driven modes; thin resistive wall; resistive wall; Fysik; Physics; Fysik;

    Abstract : A wide range of unstable current driven MHD modes is present in the re- versed τeld pinch (RFP) conτguration. An ideally conducting wall facing the plasma can stabilize the ideal MHD modes. READ MORE
