Abstract
A method for model reduction of dynamical systems
with the second order structure is proposed in this paper.
The proposed technique preserves the second order
structure of the system, and also preserves the stability
of the original systems. The method uses the
controllability and observability gramians within the
time interval to build the appropriate Petrov-Galerkin
projection for dynamical systems within the time
interval of interest. The bound on approximation error is
also derived. The numerical results are compared with
the counterparts from other techniques. The results
confirm that the method is more accurate than the
previous counterparts.
