New reachability and observability tests for positive linear discrete-time systems

T. KACZOREK
New tests (criterions) for checking the reachability and the observability of positive linear-discrete-time systems are proposed. The tests do not need checking of rank conditions of the reachability and observability matrices of the systems. Simple sufficient conditions for the unreachability and unobservability of the systems are also established.
Key words: 

discrete-time, linear, positive, system, test, reachability, observability
