Structurally Impulsive Controllablity for Descriptor Systems

In this paper, the concept of structurally impulsive controllablity is defined for descriptor systems of the form Ep¿ = Aqx + Bru, where Ep, Aq and Br are parameterized matrices, which is an extended form of structured descriptor systems [1]. Some necessary and sufficient conditions for the system to be structurally impulsive controllable are formulated algebraically. Consequently, we give an answer for structurally strong controllablity. These may be thought of as a counterpart of structurally complete (reachable) controllablity.
