...Timothy C. Allison; A. Keith Miller; Daniel J. Inman Two general linear time-varying system identification methods for multiple-input multiple-output systems are proposed based on the proper orthogonal decomposition (POD). The method applies the POD to express response data for linear or nonlinear...
