Robust tracking and model following for uncertain time-delay systems. (English) Zbl 0830.93026
Summary: A new controller design method for uncertain time-delay systems is proposed. We developed a nonlinear switching controller to force the outputs of the uncertain time-delay system to track the outputs of a non- delay reference model that represents the ideal response of the controlled uncertain time-delay system. We also demonstrate the attractiveness of the switching hypersurface and show that, along the hypersurface, the trajectories are insensitive to system parameter variations.
