Abstract

This paper presents an alternative techniques for computing linear feedback control law which stablize uncertain linear systems .Specifically, flight control system of aircraft and missiles which contains uncertain parameters. These un-certain parameters may be time varying. Their values, how, ever, are constrained to lie within known compact bounding sets. The main idea involves making Lyapunov derivative negative via a one- dimensional parameter, leading to solve algebraic Riccati equation. Several examples are included to demonstrate the importance of these techniques.
