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 bout 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 PID제어기의 개선된 동조방법을 제안한다. 이 동조방법은 내부 궤환루프에 PD 제어기를 이용하여 적분공정을 안정되게한 후, 민감도 함수 $M_{s}$를 이용하여 공정의 안전조건에 맞는 PID제어기를 동조하였다. 그리고 적분공정의 특성인 오버슈트를 줄이기 위하여 설정가중치를 갖는 PID제어기를 사용하므로 기종의 제어기가 갖는 결점을 극복했다. 제안되어진 동조 방법은 매우 간단하며 기존의 제어 동조방법보다 더 좋은 성능을 보여준다.
