  2. 1. Resource-aware Wireless Process Control

    Author : Takuya Iwaki; Karl H. Johansson; Sophie Tarbouriech; KTH; []
    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

  4. 2. 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

  5. 3. Multistage gearboxes : vibration based quality control

    Author : Johan Wändell; Hans Bodén; Ulf Carlsson; Kjell Ahlin; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Acoustics; Akustik;

    Abstract : In this thesis, vibration based techniques for detection of localised surface damages in multistage gearboxes are presented and evaluated. A modern vehicle gearbox is a complex system and the number of potential errors is large. For instance, surface damages can be caused by rough handling during assembly. READ MORE

  6. 4. Task-oriented control and coordination of multi-agent systems under varying constraints

    Author : Pian Yu; Dimos V. Dimarogonas; Carlo Fischione; Christos Cassandras; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multi-agent systems; uncertain systems; temporal logics; event-triggered control; control synthesis; conflict resolution; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Multi-agent systems (MAS) offer a tremendous potential to improve the quality of modern society life. For instance, robot networks have been widely used for providing services such as search and rescue missions, surveillance and data collection, healthcare and entertainment. READ MORE

  7. 5. On input design in system identification for control

    Author : Märta Barenthin; Bo Wahlberg; Håkan Hjalmarsson; Torkel Glad; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Systemidentifiering; Automatic control; Reglerteknik;

    Abstract : There are many aspects to consider when designing system identification experiments in control applications. Input design is one important issue. This thesis considers input design both for identification of linear time-invariant models and for stability validation. READ MORE
