摘要：
A method and system for generating reduced models of systems having time-varying elements, non-linear elements or both is provided. The system to be modeled is described utilizing differential equations (100). The differential equations of the system are then linearized (110) and the frequency domain representations of the linearized differential equations are obtained (120). A finite dimensional representation of the frequency domain representations is generated (130) and is reduced by Krylov subspace projection (140). The reduced finite dimensional representation is solved (150) to obtain the reduced model of the system.
