NEW MODEL-REDUCTION SCHEME FOR BILINEAR-SYSTEMS

A new method for the approximation of bilinear systems is proposed. Th e reduction scheme applies to both stable and unstable bilinear system s. The technique uses generalized input normal representations to reta in the dominant part of the original system. The algorithm is evaluate d on a synchronous induction generator and is shown to lead to accepta ble reduced approximations of the original system. A frequency weighti ng is also introduced in the reduction scheme to further improve the a pproximation.
