Robust control using predictor in polynomial fraction techniques

Exact model matching (EMM) in polynomial fraction techniques, which was originated by Wolovich and developed further by the author, is a very powerful design method for tracking systems. EMM system, which includes a newly developed predictor, suppresses the effect of unknown disturbance. Moreover, the predictor is very effective to suppress the more general perturbation such as unknown changing parameters, unknown parasitics, ignored higher order dynamics and/or unknown nonlinearity.<
