recommendations! Published in 2022 at "IEEE/CAA Journal of Automatica Sinica"

DOI: 10.1109/jas.2022.105692

Abstract: The core task of tracking control is to make the controlled plant track a desired trajectory. The traditional performance index used in previous studies cannot eliminate completely the tracking error as the number of time… read more here.
