Complete Rejection of Periodic Disturbances in Time-Delay Systems
The equivalent-input-disturbance(EID)approach is presented for time-delay systems with periodic disturbances in this paper.For the construction and the stability analysis with traditional equivalent-input-disturbance(EID)methodology being inadequate in time-delay systems,we propose a new configuration to reject periodic disturbances.First,we change the conventional EID estimator to be a repetitive controller to compensate for periodic disturbances.Then,to guarantee stability of the system,we present the analysis on stabilization condition with time-delay considered using linear-matrix-inequality(LMI),and derive a state feedback controller.At last,the simulation results demonstrate the validity of the proposed method by comparing with the traditional EID control method.
