THE PARAMETERIZATION OF ALL DISTURBANCE OBSERVERS

Abstract. We examine the parameterization of all disturbance observers. Disturbance observers have been used to estimate disturbances in plants. Several papers on meth-ods for designing disturbance observers have been published, however, there has been no examination of the parameterization of all disturbance observers. We propose parame-terizations of all disturbance observers and of all linear functional disturbance observers.
