  2. 1. Stochastic Event-Based Control and Estimation

    Author : Toivo Henningsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

    Abstract : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

  4. 2. 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

  5. 3. Modelling and Control Methods with Applications to Mechanical Waves

    Author : Hans Norlander; Bengt Carlsson; Torsten Söderström; Jonas Sjöberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; automatic control; pole placement; linearization; vibration control; distributed parameter systems; wave propagation; Automatic Control; Reglerteknik;

    Abstract : Models, modelling and control design play important parts in automatic control. The contributions in this thesis concern topics in all three of these concepts.The poles are of fundamental importance when analyzing the behaviour of a system, and pole placement is an intuitive and natural approach for control design.

  6. 4. Digital Work : Coping with Contradictions in Changing Healthcare

    Author : Helena Vallo Hult; Martin Gellerstedt; Katriina Byström; Tina Blegind Jensen; Högskolan Väst; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Digital work; Information Systems; physicians; professionalism; workplace learning; flipped healthcare.; Work Integrated Learning; Arbetsintegrerat lärande;

    Abstract : Digital work is bringing significant change to all professions, as established work settings are replaced by remote work and digital teamwork and collaboration. Contradictions arise when work is no longer bounded in time or space and personal and professional life merge. This raises several issues. READ MORE

  7. 5. Human–Robot Interaction Based on Motion and Force Control

    Author : Martin Karlsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Robotics; Machine Learning; Force Control; Motion Control;

    Abstract : Industrial robots typically require detailed programming and carefully configured work cells to perform well. The large engineering effort implicates high cost and long preparation time, and this is the major obstruction when mediating tasks to robots. The research in this thesis therefore aims to make robot programming faster and more accessible. READ MORE
