The control for the disturbance in the system with time delay

Abstract

The control for a disturbance adding to the input side of a plant in a system with output time delay is discussed. We aim to achieve a new approach to control the disturbance more effectively based on Smith predictor control. To obtain the disturbance information, the disturbance estimate observer is proposed. Simulation of the disturbance observer has been conducted and the characteristics of the method using the observer have been evaluated.
