  2. 1. Active Vibration Control of Multibody Systems : Application to Automotive Design

    Author : Claes Olsson; Alexander Medvedev; Stephen Elliott; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active Vibration Control; Vibration Isolation; Feedback Control; Adaptive Filtering; Saturation; Limit Cycles; Multi Body Systems; Modelling; Simulation; Non-linearity; Gain Scheduling; Structure Flexibility; Automatic control; Reglerteknik;

    Abstract : Active vibration control to reduce vibrations and structure borne noise is considered using a powerful multi-disciplinary virtual design environment which enables control system design to be considered as an integral part of the overall vehicle design. The main application studied is active automotive engine vibration isolation where, first, the potential of large frequency band multi-input multi-output H2 feedback control is considered. READ MORE

  4. 2. On Modeling and Control of Flexible Manipulators

  6. 4. Towards semi-automation of forestry cranes : automated trajectory planning and active vibration damping

    Author : Szabolcs Fodor; Leonid Freidovich; Carlos Vázquez; Anton Shiriaev; Torben Ole Andersen; Umeå universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forestry; forwarder cranes; semi-automation; slewing actuator; automated trajectory planning; oscillations; inner boom actuator; active vibration damping; frequency estimation; input shaping control technique; H2-optimal control;

    Abstract : Forests represent one of the biggest terrestrial ecosystems of Earth, that can produce important raw renewable materials such as wood with the help of sun, air and water. To efficiently extract these raw materials, the tree harvesting process is highly mechanized in developed countries, meaning that advanced forestry machines are continuously used to fell, to process and to transport the logs and biomass obtained from the forests.

  7. 5. Modeling and control of vibration in mechanical structures

    Author : Peter Nauclér; Torsten Söderström; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : All mechanical systems exhibit vibrational response when exposed to external disturbances. In many engineering applications vibrations are undesirable and may even have harmful effects. Therefore, control of mechanical vibration is an important topic and extensive research has been going on in the field over the years. READ MORE
