  3. 17. Tracking and threat assessment for automotive collision avoidance

    Författare :Andreas Eidehall; Fredrik Gustafsson; Aris Polychronopoulos; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Active safety; collision avoidance; lane guidance; state estimation; target trackin; Kalman filter; centralized filtering; threa; Automatic control; Reglerteknik;

    Sammanfattning : This thesis is concerned with automotive active safety, and a central theme is a new safety function called Emergency Lane Assist (ELA). Automotive safety is often categorised into passive and active safety, where passive safety is concerned with reducing the effects of accidents and active safety aims at avoiding them. LÄS MER

  4. 18. Non-Uniform Sampling in Statistical Signal Processing

    Författare :Frida Eng; Fredrik Gustafsson; Paulo Ferreira; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; signal processing; sampling; stochastic analysis; frequency transform; Automatic control; Reglerteknik;

    Sammanfattning : Non-uniform sampling comes natural in many applications, due to for example imperfect sensors, mismatched clocks or event-triggered phenomena. Examples can be found in automotive industry and data communication as well as medicine and astronomy. LÄS MER

  5. 19. Linear Models of Nonlinear Systems

    Författare :Martin Enqvist; Lennart Ljung; Rik Pintelon; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; linear models; nonlinear systems; system identification; stochastic processes; linearization; mean-square error; Automatic control; Reglerteknik;

    Sammanfattning : Linear time-invariant approximations of nonlinear systems are used in many applications and can be obtained in several ways. For example, using system identification and the prediction-error method, it is always possible to estimate a linear model without considering the fact that the input and output measurements in many cases come from a nonlinear system.

  7. 20. Identification and Estimation for Models Described by Differential-Algebraic Equations

    Författare :Markus Gerdin; Torkel Glad; Lennart Ljung; Manfred Deistler; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential-Algebraic Equations; Identifiability; Nonlinear systems; Modelling; Identification; Descriptor systems; Automatic control; Reglerteknik;

    Sammanfattning : Differential-algebraic equations (DAEs) form the natural way in which models of physical systems are delivered from an object-oriented modeling tool like Modelica. Differential-algebraic equations are also known as descriptor systems, singular systems, and implicit systems. LÄS MER
