Yy. Cao et al., A NEM NECESSARY AND SUFFICIENT CONDITION FOR STATIC OUTPUT-FEEDBACK STABILIZABILITY AND COMMENTS ON STABILIZATION VIA STATIC OUTPUT-FEEDBACK, IEEE transactions on automatic control, 43(8), 1998, pp. 1110-1111
In this paper, a counterexample of the above-mentioned paper(1) is rep
orted. It is pointed out that one of the conditions for a Linear syste
m to be stabilizable via static output feedback is not correct, A modi
fied necessary and sufficient condition for this problem is also prese
nted.
