The capability of ADRC is studied for linear time-invariant SISO minimum-phase systems with unknown order and unknown relative degrees. It is proved that ADRC can achieve stable tracking and zero-frequency gain being 1 for the plants with unknown but bounded relative degrees. And the knowledge of the sign of GAC is proved necessary to assure the close-loop… CONTINUE READING
