|Title:||A New Discrete-time Robust Stability Condition|
|Author:||De Oliveira M.C.|
|Abstract:||A new robust stability condition for uncertain discrete-time systems with convex polytopic uncertainty is given. It enables to check stability using parameter-dependent Lyapunov functions which are derived from LMI conditions. It is shown that this new condition provides better results than the classical quadratic stability. Besides the use of a parameter-dependent Lyapunov function, this condition exhibits a kind of decoupling between the Lyapunov and the system matrices which may be explored for control synthesis purposes. A numerical example illustrates the results. © 1999 Elsevier Science B.V. All rights reserved.|
