New results on exponential estimate for 2-D positive systems with delays
Abstract
We present a new method to the problem of finding alpha$$ \alpha $$-exponential state estimates for a class of 2-D positive discrete-time systems with bounded time-delays. A less conservative sufficient condition for the alpha$$ \alpha $$-exponential stability is derived and tighter alpha$$ \alpha $$-exponential state estimates are provided. The effectiveness of the presented method is illustrated through two numerical examples.
