    Zosta艂a zaproponowana metoda wyznaczania realizacji dodatnich dla uk艂ad贸w z op贸藕nieniami w wektorze stanu i wymuszeniu. Sformu艂owane zosta艂y warunki wystarczaj膮ce dla istnienia realizacji dodatniej danej transmitancji w艂a艣ciwej. Zaprezentowany zosta艂 algorytm komputerowy do wyznaczania realizacji na podstawie danej transmitancji w艂a艣ciwej. Dzia艂anie i efektywno艣膰 algorytmu zosta艂o zilustrowane przyk艂adem.A method for finding positive realizations of a given proper transfer function of discrete-time systems with delays in state and in inputs is proposed. Sufficient conditions for the existence of positive realizations of a given transfer function are established. A computer algorithm for computation positive realizations of a given proper transfer function is presented and illustrated by example
