Abstract:
The objective of this paper is to enhance new geometric properties which hold when the Almost Disturbance Decoupling Problem is solvable by state feedback (ADDP). The most important ones are summarized in a lattice description which, as usually, expresses algebraic relations based on sums and intersections, but also points out fundamental properties like exact or almost invariance, as well as exact or almost controllability.
