  2. 1. Incremental and Hierarchical Deadlock-Free Control of Discrete Event Systems with Variables: A Symbolic and Inductive Approach

    Author : Mohammad Reza Shoaei; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Discrete event systems; IC3; large-scale systems; model checking; incremental control; supervisory control; hierarchical control; maximal permissiveness;

    Abstract : Today's industry trend towards agile product development cycles and the ambition to shorten the time-to-market, represents an extremely competitive marketplace. This has driven the industry to use very complex and highly flexible manufacturing systems. READ MORE

  4. 2. Externally positive systems : Analysis and control based on combinatorial polynomials

    Author : Liam Hamed Taghavian; Mikael Johansson; Cristian R. Rojas; Fabio Pasqualetti; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear systems; External positivity; Optimization; Non-overshooting control; Combinatorics; Complete monotonicity; Majorization.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Monotonic tracking is required in many control systems, including those that cannot tolerate any overshoots and undershoots in their closed-loop responses. Classical examples are found in vehicle cruise control and liquid tank level control. READ MORE

  6. 4. Stochastic Event-Based Control and Estimation

    Author : Toivo Henningsson; Institutionen för reglerteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; event-based control; event-based estimation; sporadic control; stochastic control; stochastic hybrid systems; sum-of-squares methods; control over networks; quantized measurements;

    Abstract : Digital controllers are traditionally implemented using periodic sampling, computation, and actuation events. As more control systems are implemented to share limited network and CPU bandwidth with other tasks, it is becoming increasingly attractive to use some form of event-based control instead, where precious events are used only when needed.

  7. 5. Distributed control of interconnected systems and its application in traffic control

    Author : Azita Dabiri; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linear Matrix Inequality; Distributed control; Traffic flow modelling and control; Input saturation;

    Abstract : Over the past few decades, the need for mobility and road transportation has been significantly increased over the world. This turned as a dilemma in many metropolitan areas as traffic congestion costs energy and takes time of all individuals who live in big cities. READ MORE
