  1. 1. A Nonlinear Optimization Approach to H2-Optimal Modeling and Control

    Författare :Daniel Petersson; Johan Löfberg; Lennart Ljung; Roland Toth; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model reduction; LPV system; linear parameter varying; controller; control synthesis; H2; H2-norm; nonlinear optimization;

    Sammanfattning : Mathematical models of physical systems are pervasive in engineering. These models can be used to analyze properties of the system, to simulate the system, or synthesize controllers. However, many of these models are too complex or too large for standard analysis and synthesis methods to be applicable. LÄS MER

  3. 2. Nonlinear optimization approaches to H2-norm based LPV modelling and control

    Författare :Daniel Petersson; Lennart Ljung; Johan Löfberg; Henrik Sandberg; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Automatic control; Reglerteknik;

    Sammanfattning : To be able to analyze certain classes of non-linear systems, it is necessary to try to represent them as linear parameter varying systems or even as linear fractional representations. For linear parameter varying systems and linear fractional representations of systems there exists many advanced analysis methods such as IQC-analysis and μ-analysis. LÄS MER
