The mathematical formulation of the problem is motivated by the attitude control problem of an earth observation satellite with a solar panel. It is assumed that all the parameters of the plant model are uncertain and the plant single input is additively disturbed by an unknown constant torque.}, abstract={By employing the general regulator theory in the state space setup combined with the concept of the structured singular value, we develop a robustly stabilizing and robustly asymptotically tracking error feedback controller. The rotation of the main rigid body of the mechanical system is to asymptotically track a harmonically changing reference signal. The obtained theoretical results are successfully tested on two numerical examples and computations are performed in Matlab.}, type={artykuł}, title={A robust asymptotic tracking controller for an uncertain 2DOF underactuated mechanical system motivated by a satellite attitude control problem}, keywords={underactuated 2DOF mechanical system, rotational motion control, robust asymptotic tracking, robust error feedback controller}, }
