  2. 1. PID control of TITO systems

    Author : Pontus Nordfeldt; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Decoupling; PID Control; Linear Systems; Process Control; Multi-variable Control;

    Abstract : This thesis treats controller design and tuning for systems with two input signals and two output signals in the process industry. Two design methods that can be combined to form a core in an algorithm for automatic design and tuning for the considered systems are presented. READ MORE

  4. 2. PID Control, Design, Extension, Application

    Author : Helene Panagopoulos; Institutionen för reglerteknik; []

    Abstract : This thesis considers the design of PID controllers, the extensions of these controllers to improve their performance, and the applications of these design methods to industrial processes. New tuning methods for PI and PID controllers have been presented. These methods uses a model of the process to be controlled, given as a transfer function. READ MORE

  5. 3. Resource-aware Wireless Process Control

    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial process control; Networked control systems; Wireless network; Event-triggered control; Electrical Engineering; Elektro- och systemteknik;

    Abstract : To tackle the ever-growing demands on high-quality and cost-effective industrial production, recent developments in embedded sensing, wireless communication, and cloud computing offer great opportunities. Resource-aware reliable wireless communication and real-time control are needed to leverage these technologies. READ MORE

  6. 4. A Sequential Control Language for Industrial Automation

    Author : Alfred Theorin; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Grafchart; service oriented architecture; event-driven architecture; flexible production systems; industry 4.0; real-time; FMI; PID;

    Abstract : Current market trends for industrial automation are the need for customizable production, shorter time to market, and powerful global competitive pressure. Based on these trends two challenges have been identified: 1) flexible production systems and 2) integration and utilization of devices and software. READ MORE

  7. 5. Analysis and Design of Software-Based Optimal PID Controllers

    Author : Olof Garpinger; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industry; PID control; software; optimization; load disturbance attenuation; robustness; noise sensitivity; trade-off plots; modeling; friction stir welding;

    Abstract : A large process industry can have somewhere between five hundred and five thousand control loops, and PID controllers are used in 90–97% of the cases. It is well-known that only 20–30% of the controllers in the process industry are tuned satisfactorily, but with the methods available today it is considered too time-consuming to optimize each single controller.
