Abstract
An approach to modelling discrete-time systems is introduced that is motivated by transfer-function models represented in polynomial matrix form. An internal variable, referred to as the pseudo-state, captures the important signal flow information and the control and filter structures are related to this quantity. This requires the development of a new separation principle for output feedback optimal control systems
