Abstract

© 2020 Chinese Automatic Control Society and John Wiley & Sons Australia, Ltd. In this article, a highly oscillatory 3 degrees of freedom (DOF) torsional plant is used to demonstrate the effectiveness of the combined differential flatness property and active disturbance rejection control (ADRC) methodology in the output tracking of fast reference trajectory and vibration suppression problems. The controller design is synthesized in the absence of detailed knowledge of the system model, which means that the resonant modes are essentially unknown to the designer. Experimental results confirm that the excellent rest-to-rest trajectory tracking performance is attained while permanently attenuating remaining vibrations in all the three disks.
