Survey of Methods for System Identification

Single Input-Single Output (SISO) discrete filter modeling is covered first, subsequently, Multiple Input-Single Output (MISO) discrete time filters are presented.

SISO

  • Transfer function modeling [@arici2006modal ;]

MIMO

  • State-Space formulations (OKID-ERA-DC, etc [@arici2006modal])
    • System Realization by Information Matrix (SRIM) [@juang1997system]
    • Observer Kalman Filter Identification-Eigen Realization Algorithm with Direct Correlations (OKID-ERA-DC). Detailed coverage of OKID-ERA can be found in Juang (1994)
