Search for: [Abstract = "A computationally simple method for generating reduced\-order models that minimise the L2 norm of the approximation error while preserving a number of second\-order information indices as well as the steady\-state value of the step response, is presented. The method exploits the energy\-conservation property peculiar to the Routh reduction method and the interpolation property of the L2 \-optimal approximation. Two examples taken from the relevant literature show that the suggested techniques may lead to approximations that are not worse than those afforded by popular more cumbersome techniques."]
