More concretely, separable periodic 2D SISO systems are considered and state space representations by means of separable periodic Roesser models are obtained using suitable invariant formulations.engSeparable periodic 2D systemsRealization TheoryOn the state space realization of separable periodic 2D systemsjournal article10.23919/ECC.2018.8550553
