  1. 16. Afterload system design for functional donor heart assessment

    Författare :Harry Pigot; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; physiological modelling; cardiac afterload; heart assessment; working heart; simulation; control of physiological and clinical variables;

    Sammanfattning : Heart transplantation is a life-saving procedure for patients with end-stage heart failure. However, conservative acceptance criteria result in most donated hearts being discarded. Enabling clinicians to assess heart function after organ procurement can pave the way for the safe use of hearts that are currently rejected. LÄS MER

  3. 17. Continuous-time System Identification : Refined Instrumental Variables and Sampling Assumptions

    Författare :Rodrigo A. González; Cristian R. Rojas; Marion Gilson-Bagrel; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Continuous-time systems; Refined instrumental variables; band-limited signals; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Continuous-time system identification deals with the problem of building continuous-time models of dynamical systems from sampled input and output data. There are two main approaches in this field: indirect and direct. In the indirect approach, a suitable discrete-time model is first determined, and then it is transformed into continuous-time.

  4. 18. Structural Reformulations in System Identification

    Författare :Christian Lyzell; Martin Enqvist; Lennart Ljung; Alessandro Chiuso; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Dimension reduction; Subspace identification; Difference algebra;

    Sammanfattning : In system identification, the choice of model structure is important and it is sometimes desirable to use a flexible model structure that is able to approximate a wide range of systems. One such model structure is the Wiener class of systems, that is, systems where the input enters a linear time-invariant subsystem followed by a time-invariant nonlinearity. LÄS MER

  7. 20. On some continuous-time modeling and estimation problems for control and communication

    Författare :Yasir Irshad; Magnus Mossberg; Magnus Jansson; Karlstads universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System Identification; Parameter Estimation; Continuous-time Stochastic Systems; Networked Control Systems; Errors-in-variables Systems; Wireless Channel Modeling; Closed-loop Identification; Physics; Fysik;

    Sammanfattning : The scope of the thesis is to estimate the parameters of continuous-time models used within control and communication from sampled data with high accuracy and in a computationally efficient way.In the thesis, continuous-time models of systems controlled in a networked environment, errors-in-variables systems, stochastic closed-loop systems, and wireless channels are considered.
