[en] In this paper, a new robust unifiedH∞ dynamic observer (UDO) design for systems in the presence of time-varying uncertainty and disturbances is presented. The observer design method is derived from the solution of the liner matrix inequality (LMI), based on the solution of the algebraic constraint obtained from the analysis of the estimation error. A numerical example is presented to show the performance of the proposed observer.
