Systems and methods for rational function fitting in model generation

Abstract:

Systems and methods are provided for generating a state space model of a physical system. Embodiments of a computer-implemented system may include a physical system data structure that includes frequency-domain response data that is indicative of a response of one or more components of a physical system to a stimulus, and a state space model generation engine that is configured generate a state space model based on the frequency-domain response data, where the state space model is usable to simulate a time-domain response of the one or more components of the physical system.
