The problem of observing the state of a two-dimensional system in the presence of unknown disturbance noise is considered. The Roesser state-space model is used to represent the two-dimensional system. Conditions are given for the existence of an observer capable of producing an asymptotic estimate of the state of the given system. Furthermore, conditions are presented for being able to choose the form of the observer in a simple form such that the transfer function has a separable denominator. Finally, design equations are developed for calculation of the observer matrices in the simple form where singular value decomposition is used to formulate the technique.
