  1. 1. A Graphical Language for Batch Control

    University dissertation from Department of Automatic Control, Lund Institute of Technology (LTH)

    Author : Charlotta Johnsson; [1999]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automation; Batch Recipes; Batch Processes; Sequential Control; Grafcet; Petri nets; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : 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. READ MORE

  2. 2. Batch Control and Diagnosis

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Abstract : Shikimic acid production using recombinant E.coli has been developed during the past 15 years due to the increased demand of this product, primarily as a starting material for the anti-influensa medicine Tamiflu?. A detailed metabolic analysis of a shikimic acid producing E. READ MORE

  5. 5. Recipe-Based Batch Control Using High-Level Grafchart

    University dissertation from Department of Automatic Control, Lund Institute of Technology, Lund University

    Author : Charlotta Johnsson; [1997]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Batch control; Grachart;

    Abstract : 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. READ MORE
