✦ Synopsis

High order state variable models of chemical processes can be reduced to lower order models by matching the moments of the impulse responses for those states which it is desired to retain. The moments of the full model are calculated directly from the state equations and the parameters of the reduced model are calculated from these moments. The method places no restriction on the choice of outputs and all the inputs are retained.

A generalized formulation of the generalized moment method is used to reduce a IOth-order power system model to 4th-order. The results are compared to those obtained by Bandekas and Papadopoulos who recently attempted to solve the same problem. Results obtained using balanced model reduction are als
