Abstract
An observer is introduced for state estimation of nonlinear deterministic systems. The observer gain is computed by a Riccati differential equation similar to the extended Kalman filter. The modification of the Riccati differential equation for the proposed observer is based on the application of H∞-filtering and robust control methods, which allows an effective treatment of the nonlinearities. Thus, the high performance of the extended Kalman filter can be further improved
