  2. 6. On Model Simplification in System Identification

    Author : Bo Wahlberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model simplification; System identification;

    Abstract : This report deals with the connection between system identification and model reduction. We propose an identification algorithm that is based on the least squares identification method and either of the model reduction techniques: Frequency weighted truncated balanced realization or frequency weighted optimal Hankel-norm model reduction.

  4. 7. Continuous-time System Identification : Refined Instrumental Variables and Sampling Assumptions

    Author : Rodrigo A. González; Cristian R. Rojas; Marion Gilson-Bagrel; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Continuous-time systems; Refined instrumental variables; band-limited signals; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Continuous-time system identification deals with the problem of building continuous-time models of dynamical systems from sampled input and output data. There are two main approaches in this field: indirect and direct. In the indirect approach, a suitable discrete-time model is first determined, and then it is transformed into continuous-time.

  5. 8. Regressor and Structure Selection : Uses of ANOVA in System Identification

    Author : Ingela Lind; Lennart Ljung; Torsten Söderström; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Regressor selection; Analysis of variance; Nonlinear systems; Structure selection; Automatic control; Reglerteknik;

    Abstract : Identification of nonlinear dynamical models of a black box nature involves both structure decisions (i.e., which regressors to use and the selection of a regressor function), and the estimation of the parameters involved. READ MORE

  7. 10. On Application Oriented Experiment Design for Closed-loop System Identification

    Author : Afrooz Ebadat; Bo Wahlberg; Torsten Söderström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; system identification; closed-loop identification; experiment design for identification;

    Abstract : System identification concerns how to construct mathematical models of dynamic systems based on experimental data. A very important application of system identification is in model-based control design. In such applications it is often possible to externally excite the system during the data collection experiment. READ MORE
