AbstractThe concepts of {A,E,R(B)} and restricted {E,A,R(B)} invariance are introduced. The reachable subspace of a descriptor system is shown to be the supremal {A,E,R(B)}invariant subspace contained in the least restricted {E,A,R(B)} subspace of Rn. Algorithms to compute the reachable subspace of a descriptor system
$$Edot x = Ax + Bu$$
in terms ofE,A andB are given. A new proof of the feedback invariance of the reachable subspace is presented.
