The problem of unknown and unmeasurable arbitrary disturbance rejection along with reference signal tracking or model following is one of the most important in control theory. The most widely used methods which may be treated as disturbance attenuation use the available a priori information about disturbances in statistical or uncertain (set-membership) form. In most practical applications the typical situation is characterized by the lack of a priori information, which is quite enough for disturbance modeling. In such a case it is expedient to use the current information about disturbances obtained by direct or indirect measurements. Such an approach realized in combined feedback/feedforward control structures can provide a significant increase of control accuracy.
