Tracking of discrete-time unmodeled reference signals in robotic manipulators using output regulation theory and high-gain observers

Abstract: In the field of control, output regulation theory ensures the tracking of reference signals generated by a known dynamic exogenous system, referred to as the exosystem. However, there are ...
