An H∞ smoother has been developed (Blanco et al., 2000) and it gives good results for noise uncertainties. Nevertheless, when uncertain parameters appear, its performance decreases significantly. Therefore, an estimator robust to noise uncertain properties and parameter uncertainties is presented. The robust H∞ smoother for uncertain systems is developed as a combination of two robust H∞ filters. The robust performance, for both noise and parameter uncertainties, of this new approach is evaluated on a simple example
