In-block controllability of affine systems on polytopes

MK Helwa, PE Caines - IEEE Transactions on Automatic …, 2016 - ieeexplore.ieee.org
In this technical note, we introduce the study of the in-block controllability (IBC) of affine
systems on polytopes. In particular, we study whether all the states in the interior of a given …

Relaxed in-block controllability of affine systems on polytopes

MK Helwa, PE Caines - 53rd IEEE Conference on Decision and …, 2014 - ieeexplore.ieee.org
We consider affine systems defined on polytopes and study the cases where the systems
are not in-block controllable with respect to the given polytopes. Instead, we introduce in this …
