A Controller Tuning Method by Pade Second Order Approximation

파데 2차 근사방법을 사용한 제어기기의 동조

The controller tuning methods proposed by Yuwana-Seborg and Suh utilizes Pade first order approximation for the delay terms in the closed loop transfer function. In this paper, the use of a Pade second-order approximation method is investigated. The simulation results show that the new method is superior to pervious approaches such as Ziegler-Nichols and Cohen-Coon methods.
