Repetitive control of servo systems with time delays ?
A novel repetitive control is proposed for the system with delays in control channels. Precise tracking and/or rejection of periodic signals are achieved. Only two parameters are required to be selected for control design. Sufficient stability conditions and the robustness analysis are studied. Simulation and experiments are provided to show the practicality of the design.
