Necessary and Suffcient Conditions for Distinguishability of Linear Control Systems
《Acta Mathematicae Applicatae Sinica》2014年第2期473-482,共10页Hong-wei LOU Rong YANG 
Supported in part by the National Natural Science Foundation of China under Grant(No.61074047 and No.10831007);National Basic Research Program of China(973 Program)(No.2011CB808002)
Distinguishability plays a crucial rule in studying observability of hybrid system such as switched system. Recently, for two linear systems, Lou and Si gave a condition not only necessary but also sufficient to the d...
