영문 초록

Many control techniques have been proposed in order to improve the control performance of the control system. The degree of freedom on control in the control system is decided by the number of the closed-loop transfer function which can adjust independently. The controller design scheme with two degrees of freedom(TDOF) is extensively used for securing the good control performance to trace a desired value and reject disturbance. In this paper, for constructing the controller to improve the quick response in starting and to be robust on disturbance or a load variation, PID controller is used by controller with TDOF and the design method for control system with TDOF is proposed. The method which can cancel the poles and zeros on the transfer function of a control system is proposed and we reduced the order of the transfer function of a control system. The usefulness of the proposed algorithm is proved by the simulation. With the simulation results, it was made clear that the introduction of two degrees of freedom controller designed by the proposed method not only improves the over shoot and starting characteristic of response but also removes the undesirable characteristic variation on a load variation.
