Analysis on Controllability of Descriptor Systems under Structural Decomposition

Controllability is an important property of linear systems. In this paper, we analyze the controllability, R-controllability and impulse controllability of descriptor systems under the structural decomposition, which presented by Chen and He [5]. We give some controllability criterions under structural decomposition and prove them completely. We also present an equivalent condition for impulse controllability of descriptor systems at the end of this paper.
