  2. 1. Resource Management in Computing Systems

    Author : Payam Amani; Bredbandskommunikation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Resource management is an essential building block of any modern computer and communication network. In this thesis, the results of our research in the following two tracks are summarized in four papers. The first track includes three papers and covers modeling, prediction and control for multi-tier computing systems. READ MORE

  4. 2. Direct-Ground Cooling Systems for Office Buildings: Design and Control Considerations

    Author : Taha Arghand; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Borehole; Cooling capacity; Laboratory experiments; Ground heat exchanger; Fluid temperature levels; Control; Direct-ground cooling; Optimization; High temperature cooling;

    Abstract : Direct-ground cooling systems are defined as systems in which the ground is used as the only source for cooling mainly in commercial buildings. These systems benefit from exchanging heat with the ground, of which its temperature is basically constant below a certain depth year around. READ MORE

  5. 3. The reinforcement learning method : A feasible and sustainable control strategy for efficient occupant-centred building operation in smart cities

    Author : Ross May; Kenneth Carling; Mengjie Han; Pascal Rebreyend; Zoltan Nagy; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Markov decision processes; Reinforcement learning; Control; Building; Indoor comfort; Occupant; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Abstract : Over half of the world’s population lives in urban areas, a trend which is expected to only grow as we move further into the future. With this increasing trend in urbanisation, challenges are presented in the form of the management of urban infrastructure systems. READ MORE

  6. 4. Distributed Control for Spatio-Temporally Constrained Systems

    Author : Adrian Wiltz; Dimos V. Dimarogonas; Jonas Mårtensson; Matthias Müller; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; distributed model predictive control; control barrier functions; spatio-temporal constraints; constrained control; multiagent systems; distribuerad modell prediktiv styrning; kontrollbarriärfunktion; tillstånds-temporala begränsningar; begränsade system; multiagentsystem;

    Abstract : In this thesis, we develop methods leading towards the distributed control of spatio-temporally constrained systems. Overall, we focus on two different approaches: a model predictive control approach and an approach based on ensuring set-invariance via control barrier functions. READ MORE

  7. 5. Design, Implementation and Validation of Resource-Aware and Resilient Wireless Networked Control Systems

    Author : José Araújo; Karl H. Johansson; Jan Lunze; KTH; []
    Keywords : wireless networked control systems; NCS; wireless communications; control; distributed reconfiguration; resilient; fault-tolerant control; IEEE 802.15.4; resource-aware; WNCS; aperiodic control; event-triggered; self-triggered; event-based; co-simulator; estimation; GISOO; MAC; scheduling; routing; RPL; delay; out-of-order communications; CPS; Cyber Physical Systems; Wireless Cyber Physical Systems; Wireless Cyber Physical Control Systems; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Networked control over wireless networks is of growing importance in many application domains such as industrial control, building automation and transportation systems. Wide deployment however, requires systematic design tools to enable efficient resource usage while guaranteeing close-loop control performance. READ MORE
