적분공정을 위한 민감도 함수 MS를 이용한 안정된 PID 동조 = Stable PID Tuning for Integrating Processes using sensitive function MS

다국어 초록 (Multilingual Abstract)

PID control is windely used to control stable processes, however, its application to integrating processes is less common. In this paper, we proposed a simple PID controller tuning method for integrating processes with time delay to meet a stable specification. With the proposed PID tuning method, we can obtain stable integrating processes using PD controller in inner feedback loop and a loop transfer function with desired stable specification. This guarantees both robustness and performance. Simulation examples are given to show the good performance of the proposed tuning method to other methods.

본 논문에서는 적분공정이 안정한 조건을 갖게 하는 설정가중치를 갖는 PID제어기[1]의 개선된 동조방법을 제안한다. 이 동조방법은 내부 궤환루프에 PD 제어기를 이용하여 적분공정을 안정되게한 후, 민감도 함수 를 이용하여 공정의 안정조건에 맞는 PID제어기를 동조하였다. 그리고 적분공정의 특성인 오버슈트를 줄이기 위하여 설정가중치를 갖는 PID제어기를 사용하므서 기존의 제어기가 갖는 결점을 극복했다. 제안되어진 동조 방법은 매우 간단하며 기존의 제어 동조방법보다 더 좋은 성능을 보여준다.
