By using the Lyapunov function method, the absolute robust stability of the uncertain Lurie direct control system and the indirect control system with structural perturbations and norm disturbances are discussed. The sufficient conditions for the robust robust stability of the system are also given. The interval L urie direct control system and the indirect control system are of absolute robust stability. The conclusion given in this paper is the linear matrix inequality form (LMI), which can be easily solved by Matlab toolbox. Finally, Examples are compared with previous results
