“…The researchers then obtained a preview controller based on preview control theory. However, it was pointed out that the discrete lifting technique may lead to "dimension disaster," especially for systems with large delays [23,32]. Therefore, this paper further studies the preview control problem of linear systems with input delay.…”

This paper presents a method for designing a type one servomechanism for a discrete-time linear system with input delay subject to a previewable desired output and a nonmeasurable constant disturbance. The tracking problem of a delay system is transformed into a regulation problem of a delay-free system via constructing an augmented error system and a variable substitution. A controller is obtained with delay compensation and preview compensation based on preview control theory and the predictor method. When the state vector is not directly measurable, a full-dimensional observer is offered. The effectiveness of the design method is demonstrated by numerical simulations.
