  1. 1. 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.

  4. 3. On Optimal Integrated Task and Motion Planning with Applications to Tractor-Trailers

    Författare :Anja Hellander; Daniel Axehill; Martin Enqvist; Kristoffer Bergman; Yiannis Karayiannidis; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : An important aspect in autonomous systems is the ability of a system to plan before acting. This includes both high-level task planning to determine what sequence of actions to take in order for the system to reach a goal state, as well as low-level motion planning to detail how to perform the actions required.

  5. 4. Some results on closed-loop identification of quadcopters

    Författare :Du Ho; Martin Enqvist; Gustaf Hendeby; Alexander Medvedev; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In recent years, the quadcopter has become a popular platform both in research activities and in industrial development. Its success is due to its increased performance and capabilities, where modeling and control synthesis play essential roles. LÄS MER

  7. 5. Estimation of Inverse Models Applied to Power Amplifier Predistortion

    Författare :Ylva Jung; Martin Enqvist; Lennart Ljung; Torkel Glad; Mikael Sternad; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Mathematical models are commonly used in technical applications to describe the behavior of a system. These models can be estimated from data, which is known as system identification. Usually the models are used to calculate the output for a given input, but in this thesis, the estimation of inverse models is investigated. LÄS MER
