Decomposition of the positive fractional discrete- time linear system
Abstract
The decomposition of unreachable positive fractional discrete-time linear systems into the reachable and unreachable parts is addressed. Conditions for the decomposition of the unreachable system into reachable and unreachable parts are established. A procedure for the decomposition is proposed and illustrated by numerical examples.
Keywords
fractional discrete-time linear systems, Kalman's decomposition
