  5. 23. On Distributed Control-by-Wire Systems for Critical Applications

    Author : Roger Johansson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; time-triggered communication; fault-tolerance; distributed systems; dependable systems; inherent redundancy; control-by-wire;

    Abstract : The implementation of closed loop control systems is an important field for the exploitation of embedded real-time computer systems. One can find a particularly interesting class of closed loop control applications within vehicle dynamics control. READ MORE

  6. 24. On circularity in production systems : Exploring the realization through circularity practices

    Author : Filip Skärin; Carin Rösiö; Ann-Louise Andersen; Anna Sannö; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circularity; circular economy; production systems; circularity practices; manufacturing; industry; reconfigurability; sustainability; cirkularitet; cirkulär ekonomi; produktionssystem; tillverkning; industri; rekonfigurerbarhet; hållbarhet;

    Abstract : The manufacturing industry stands in front of huge challenges. Negative environmental impacts must be drastically reduced and new sustainable products must be introduced at an accelerating pace. Coping with these challenges are significant in order to deal with the increasingly emerging climate crisis. READ MORE

  7. 25. Design of Optimal Control Processes for Closed-Loop Chain SCARA-Like Robots

    Author : Mathias R Lidberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; unpowered actuator.; SCARA-robot; closed-loop chain; manipulator;

    Abstract : The design of optimal control processes for closed-loop chain SCARA-like robots is the subject of this thesis. In comparison with the well-known SCARA robot, the proposed new structure is characterized by the incorporation of an additional powered actuator, several unpoweredactuators and an additional link that gives a closed-loop chain robot.
