  4. 3. Recipe-Based Batch Control Using High-Level Grafchart

    Författare :Charlotta Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Batch control; Grachart;

    Sammanfattning : High-Level Grafchart is a graphical programming language for control of sequential processes. Sequential control is important in all kinds of industries: discrete, continuous and batch. Sequential elements show up both on the local control level and on the supervisory control level. LÄS MER

  5. 4. A Graphical Language for Batch Control

    Författare :Charlotta Johnsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Batch Recipes; Batch Processes; Sequential Control; Grafcet; Petri nets; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Sammanfattning : In this thesis a graphical language for sequential control is presented and its application to batch control is examined and discussed. The name of the language is Grafchart. Its main feature is that it makes it possible to express complicated control problems in a compact and intuitive manner. LÄS MER
