Abstract :
The robust stability problem of a convex hull of a finite number of matrices was treated in the above-titled paper by Y.K. Foo and Y.C. Soh (ibid., vol.35, no.11, p.1257-9, Nov. 1990), and a sufficient condition was presented. The commenters give another sufficient condition and show, using an example, that their condition can be less conservative than the result. They also give a necessary and sufficient condition for the robust stability problems treated by Foo and Soh.<>
