Corrigendum to: "Time-relevant stability of 2D systems" [Automatica 47 (11) (2011) 2373-2382]

This note corrects some errors and misprints in Napp, Rapisarda, and Rocha (2011). The condition for time-relevant stability given in Theorem 10 is sufficient, but not necessary. Therefore the following changes should be made. In the statement of Theorem 10, ‘‘if and only if’’ should be replaced by ‘‘if’’. In the proof of the ‘‘if’’ part of this theorem, the sentence ‘‘In order to do this, since . . . if and only if . . .’’ should read ‘‘In order to do this, since . . . if . . .’’. Moreover, the ‘‘only if’’ part of the proof should be eliminated. In the statements of Proposition 15 and Theorem 17, the sentence ‘‘Then the following statements are equivalent: (1) B is time-relevant stable;’’ should be replaced by ‘‘Then the following statements are equivalent and imply that B is time-relevant stable’’.
