In this paper, a model reduction technique based on optimization is presented. The objective function minimized is the impulse energy of the overall system. An extension of the technique to the frequency weighted case is also presented, where single-sided or double-sided weightings can be incorporated in the reduction procedure. The paper proposes an alternative to find an optimization solution by solving ordinary differential equations which are gradient flow associated with the objective function to be minimized. Two examples are presented to illustrate the effectiveness of the method.
