  2. 21. A Graphical Language for Batch Control

    Author : Charlotta Johnsson; Institutionen för reglerteknik; []
    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

  4. 22. Model Predictive Control in Flight Control Design : Stability and Reference Tracking

    Author : Daniel Simon; Johan Löfberg; Sébastien Gros; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model Predictive Control;

    Abstract : Aircraft are dynamic systems that naturally contain a variety of constraints and nonlinearities such as, e.g., maximum permissible load factor, angle of attack and control surface deflections. READ MORE

  5. 23. Aging sensitive battery control

    Author : Malin Andersson; Mikael Johansson; Matteo Corno; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lithium-ion battery; battery control; parameter identification; equivalent circuit model; Doyle-Fuller-Newman model; sensitivity analysis; optimal experiment design; Electrical Engineering; Elektro- och systemteknik;

    Abstract : The battery is a component with significant impact on both the cost and environmental footprint of a full electric vehicle (EV). Consequently, there is a strong motivation to maximize its degree of utilization. Usage limits are enforced by the battery management system (BMS) to ensure safe operation and limit battery degradation. READ MORE

  6. 24. Modelling, analysis and experimentation of a simple feedback scheme for error correction control

    Author : Oscar Flärdh; Karl H. Johansson; Mikael Johansson; Bo Bernhardsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Network Control; Error Correction; Multiple-Input Describing Function; Extremum Seeking Control; Sensor Network Experiments; Automatic control; Reglerteknik;

    Abstract : Data networks are an important part in an increasing number of applications with real-time and reliability requirements. To meet these demands a variety of approaches have been proposed. Forward error correction, which adds redundancy to the communicated data, is one of them. READ MORE

  7. 25. Development and evaluation of methods for control of multiple-input multiple output systems

    Author : Fredrik Bengtsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hold-input; Unreliable communication links; Decentralized control; MIMO systems.; Delays; LQG control; Input-output scaling; Control configuration selection; Gramian based measures;

    Abstract : In control, the most common type of system is the multiple-input multiple-output (MIMO) system, where the same input may affect multiple outputs, or conversely, the same output is affected by multiple inputs. In this thesis two methods for controlling MIMO systems are examined, namely linear quadratic Gaussian (LQG) control and decentralized control, and some of the difficulties associated with them.
