Abstract :
Passivity of an identified model is crucial in simulation and prediction applications. This paper proposes a two-step procedure that generates guaranteed passive transfer function models from noisy data. It consists of an unconstrained optimal noise removal step, followed by passivity enforcement of the unconstrained model.
