Abstract :
Geometric properties of null controllable region of discrete-time switched linear systems with input saturation are studied. We show that the null controllable region is not convex in general and is centrally symmetric. Under certain conditions, it can be well approximated by a nondecreasing region sequence. It is also shown that the null controllable region is contained in the Minkowski sum of null controllable regions of all its sub-switched systems
