Design of the optimum preview controller for a class of state-delay systems

This paper studied the design of the optimum preview controller used for a class of state-delay systems. Difference method was first introduced to translate the time-delay system into a common system without time-delay, and then the theory of preview control for a system without time-delay was used to design the controller. The sufficient conditions for the designed controller were proposed. The efficiency of this feedforward compensation method was testified through an emulational example.
