Performance-recoverable intelligent digital redesign for fuzzy tracking controllers
Performance-recoverable intelligent digital redesign (IDR) in a fast sampling limit is proposed for fuzzy tracking controllers with time-varying references. IDR uses a delta operator and a piecewise linearrather than constantapproximation of the reference improve the state-matching performance for both an extremely small and a large sampling period T?R>0 T ? R > 0 , respectively. It is proved that the analog control performance is recovered by the proposed intelligently digitally redesigned sampled-data controller in three perspectivescontroller gain, stability, and closed-loop trajectorywhen T goes to zero.
