  1. 36. Hybrid observers for systems with intrinsic pulse-modulated feedback

    Författare :Diana Yamalova; Alexander Medvedev; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : This licentiate thesis deals with a special class of hybrid systems, where the continuous linear part is controlled by an intrinsic impulsive feedback that contributes discrete dynamics. The impacting pulsatile feedback signal is not available for measurement and, therefore, has to be reconstructed. LÄS MER

  3. 37. Feedback and adjoint based control of boundary layer flows

    Författare :Mattias Chevalier; Dan Henningson; Jean-Marc Chomaz; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; fluid and plasma; mechanical engineering; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Linear and nonlinear optimal control have been investigated in transitional channel and boundary layer .ows. The flow phenomena that we study are governed by the incompressible Navier–Stokes equations and the main aim with the control is to prevent transition from laminar to turbulent flows. LÄS MER

  4. 38. Feedback Control and Sensor Fusion of Vision and Force

    Författare :Tomas Olsson; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; sensor based robot control; Visual tracking; visual servoing; resource optimization; Kalman filter;

    Sammanfattning : This thesis deals with feedback control using two different sensor types, force sensors and cameras. In many tasks robotics compliance is required in order to avoid damage to the workpiece. Force and vision are the most useful sensing capabilities for a robot system operating in an unknown or uncalibrated environment. LÄS MER

  5. 39. Adaptive Modulation and Coding in Wireless Communications with Feedback

    Författare :Sorour Falahati; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : We study link adaptation techniques which are suitable for the future packet-based wireless communication systems, where in particular, flat Rayleigh fading channels are assumed. Firstly, an adaptive coding scheme based on Rate Compatible Convolutional (RCC) codes is proposed. LÄS MER

  7. 40. State-based Channel Access for a Network of Control Systems

    Författare :Chithrupa Ramesh; Karl Henrik Johansson; Henrik Sandberg; Joao Hespanha; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; networked control; multiple access; event-based; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Wireless networked control systems use shared wireless links to communicate between sensors and controllers, and require a channel access policy to arbitrate access to the links. Existing multiple access protocols perform this role in an agnostic manner, by remaining insular to the applications that run over the network. LÄS MER
