  1. 6. Nonlinear Identification and Control with Solar Energy Applications

    Författare :Linda Brus; Bengt Carlsson; Torbjörn Wigren; Graham C. Goodwin; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; feedforward control; model predictive control; nonlinear control; nonlinear systems; recursive identification; solar power; system identification; time delay systems; Automatic control; Reglerteknik; Reglerteknik; Automatic Control;

    Sammanfattning : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. LÄS MER

  3. 7. Recursive black-box identification of nonlinear state-space ODE models

    Författare :Linda Brus; Bengt Carlsson; Torbjörn Wigren; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Sammanfattning : Nonlinear system identification methods is a topic that has been gaining interest over the last years. One reason is the many application areas in controller design and system development. However, the problem of modeling nonlinear systems is complex and finding a general method that can be used for many different applications is difficult. LÄS MER

  4. 8. Rigid Body Ship Dynamics

    Författare :Martin Alexandersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inverse dynamics; Extended Kalman filter; Ship digital twin; Ship manoeuvring; RTS smoother; Multicollinearity; System identification;

    Sammanfattning : It is common today that operational data is recorded onboard ships within the Internet of Ships (IoS) paradigm. This enables the possibility to build ship digital twins as digital copies of the real ships. Predicting the ship’s motions with ship dynamics could be an important sub-component of these ship digital twins. LÄS MER

  5. 9. Bayesian Inference for Nonlinear Dynamical Systems : Applications and Software Implementation

    Författare :Jerker Nordh; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Indoor Navigation; pyParticleEst; Software Implementation; Simultaneous Localization and Mapping; Parameter Estimation; System Identification; Sequential Importance Sampling; Particle Filter; Bayesian Inference; Markov Chain Monte Carlo; Particle Smoother;

    Sammanfattning : The topic of this thesis is estimation of nonlinear dynamical systems, focusing on the use of methods such as particle filtering and smoothing. There are three areas of contributions: software implementation, applications of nonlinear estimation and some theoretical extensions to existing algorithms. LÄS MER

  7. 10. Core-box Modelling - Theoretical Contributions and Applications to Glucose Homeostasis Related Systems

    Författare :Gunnar Cedersund; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The study of biological systems through a combination of in vitro characterisations, quantitative in vivo experiments, and mathematical modelling, is receiving an increasingly growing interest through the field system biology. Systems biology uses methods from many different research fields, but the existing methods need to be extended and adapted to fit the new situations. LÄS MER
