Necessary and sufficient conditions for distinguishability of linear control systems
From the summary: Distinguishability plays a crucial rule in studying observability of hybrid systems such as switched systems. Recently, for two linear systems, Lou and Si gave a condition not only necessary but also sufficient for the distinguishability of linear systems. However, the condition is not easy enough to verify. This paper gives a new equivalent condition which is relatively easy to verify.
