  1. 1. Parameter Estimation in Linear Descriptor Systems

    Författare :Markus Gerdin; Linköpings universitet; []
    Nyckelord :differential-algebraic equations; descriptor systems; identification; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Linear descriptor systems form the natural way in which linear models of physical systems are delivered from an object-oriented modeling tool like Modelica. Linear descriptor systems are also known as linear differential-algebraic equations in the continuous-time case. LÄS MER
