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 reduce

## Abstract This paper describes a method for obtaining a time continuous reduced order model (ROM) from a system of time continuous linear differential equations. These equations are first put into a time discrete form using a finite difference approximation. The unit sample responses of the discr
