Abstract

The analysis of disturbance rejection for singe-input singe-output (SISO) Lur'e system with norm uncertainty was concerned through invariant set analysis using Liapunov function method. The conditions on robust ellipsoidal attractor for uncertain Lur'e systems were given in terms of LMIs (Linear Matrix Inequality), which simultaneously ensure the absolute stability and disturbance rejection of the uncertain Lur'e systems. An estimate of the maximum set included in a robust ellipsoidal attractor was also presented. Finally, a numerical example was worked out to illustrate the main results.
