  2. 6. Efficiency of building related pump and fan operation - Application and system solutions

    Author : Caroline S Markusson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; motor drive; control-on-demand; hydronic systems; air systems; electric motor; variable speed; decentralized systems; pump; electric energy; fan; local systems; efficiency;

    Abstract : The electric energy use in Swedish non-industrial buildings is 71 TWh per year out of which 30 TWh per year is used for the operation of technical systems. A significant part of those 30 TWh/year is used for pump and fan operation. The Swedish parliament decided in 2009 on a national energy and climate plan. READ MORE

  4. 7. 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

  5. 8. Funnel-Based Control for Coupled Spatiotemporal Specifications

    Author : Farhad Mehdifar; Dimos V. Dimarogonas; Charalampos P. Bechlioulis; Bayu Jayawardhana; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Funnel-Based Control; Prescribed Performance Control; Uncertain Nonlinear Systems; Time-Varying Output Constraints; Coupled Spatiotemporal Constraints; Formation Control; Multi-Agent Systems; Trattbaserad kontroll; föreskriven prestandakontroll; osäkra icke-linjära system; tidsvarierande utgångsbegränsningar; kopplade rumsliga begränsningar; formationskontroll; multiagentsystem; Electrical Engineering; Elektro- och systemteknik;

    Abstract : In the past decade, the integration of spatiotemporal constraints into control systems has emerged as a crucial necessity, driven by the demand for enhanced performance, guaranteed safety, and the execution of complex tasks. Spatiotemporal constraints involve criteria that are dependent on both space and time, which can be represented by time-varying constraints in nonlinear control systems. READ MORE

  6. 9. 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. 10. Demand based control of indoor climate in office buildings. Design of local and central feed-forward control systems for high comfort, low energy use and low peak power

    Author : Mattias Gruber; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; demand based control; IAQ; central control; local control; disturbance rejection; thermal climate; HVAC; energy efficiency; feed-forward; Building services engineering; office buildings;

    Abstract : In this work, a number of novel strategies for controlling the heating, ventilation and air-conditioning (HVAC) systems in office buildings have been designed and evaluated. The purpose of the control strategies is to improve the match between what is supplied by the HVAC-systems and what is required to achieve a desirable indoor climate in the building. READ MORE
