  1. 16. Stochastic Invariance and Aperiodic Control for Uncertain Constrained Systems

    Författare :Yulong Gao; Karl H. Johansson; Alessandro Abate; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; controlled invariant set; stochastic system; constraint; uncertainty; reachable set; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Uncertainties and constraints are present in most control systems. For example, robot motion planning and building climate regulation can be modeled as uncertain constrained systems. In this thesis, we develop mathematical and computational tools to analyze and synthesize controllers for such systems. LÄS MER

  3. 17. Optimizing Ocean Feature Estimation and Tracking through Adaptive Sampling and Formation Control of Autonomous Underwater Vehicles

    Författare :Joana Filipa Gouveia Fonseca; Karl H. Johansson; Nina Mahmoudian; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Increased ocean temperatures caused by climate change are expected to lead to more frequent and severe harmful algal blooms, which deteriorate water quality, cause human illness and fish mortality. Scientific understanding of algal blooms and their dynamics is limited due to the lack of data from such ocean phenomena. LÄS MER

    Sammanfattning : Wireless networks in industrial process control enable new system architectures and designs. However, wireless control systems can be severely affected by the imperfections of the communication links. LÄS MER

  5. 19. Resource-aware Wireless Process Control

    Författare :Takuya Iwaki; Karl H. Johansson; Sophie Tarbouriech; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial process control; Networked control systems; Wireless network; Event-triggered control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : 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. LÄS MER

  7. 20. Wireless Sensor Network Scheduling and Event-based Control for Industrial Processes

    Författare :Takuya Iwaki; Karl H. Johansson; Vijay Gupta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Networked control systems; Wireless sensor and actuator network; Event-based control; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Control over wireless sensor and actuator networks is of growing interest in process industry since it enables flexible design, deployment, operation, and maintenance. An important problem in industrial wireless control is how to limit the amount of information that needs to be exchanged over the network. LÄS MER
