This paper is concerned with disturbance rejection analysis of structured uncertain Lur’e systems through invariant set analysis using Lyapunov function method. The conditions on robust ellipsoidal attractor for uncertain Lur’e systems are presented in terms of LMIs, which simultaneously ensure absolute stability and disturbance rejection of Lur’e systems. An estimate of the maximum set included in a robust ellipsoidal attractor is presented. Finally, a numerical example is worked out to illustrate the main results.
