    Abstract : Fusion welding for joining of metals is an important manufacturing process widely used in industry, and very appreciated for its usefulness. This thesis presents a strategy dealing with the problem of designing feedback control for robotised welding. READ MORE

  7. 15. A Simulation-Based Optimisation Method for PLC Systems

    Author : Bo Svensson; Bengt Lennartson; Rolf Bernhardt; Högskolan Väst; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Simulation based optimisation; Virtual manufacturing; Industrial control system; PLC; Continuous simulation; Parameter tuning; Optimisation methods; Manufacturing and materials engineering; Produktions- och materialteknik;

    Abstract : Tuning of process parameters such as time constants, cam values, velocities and robot paths, in order to increase capacity utilisation, is today a challenging manual on-line task in many automated manufacturing systems. On-line methods interfere with production and will cause unwanted downtime, which indeed reduces capacity utilisation. READ MORE
