  • Abstract
    In this paper the problem of determining necessary and sufficient conditions for the Lyapunov function for a pair of stable linear time-invariant systems whose system matrices, A1, A2, are in companion form is considered. It is shown that a necessary and sufficient condition for the existence of such a function is that the matrix product A1A2 does not have an eigenvalue that is real and negative. Examples are presented to illustrate the result.
