Abstract

In this paper, a method for IMC-PID controller tuning is proposed based on obtaining a controller from closed-loop transfer function. It is considered a plant with the second-order plus dead time(SOPDT) model and selected the third-order plus dead time transfer function model as a target function. The filter function is derived from the suitable target function to satisfy the design specifications. A robustness test was done to verify the robust-stability.

본 논문에서는 폐 루프 전달함수로부터 제어기를 얻는 방법에 기초한 IMC-PID 제어기 동조방법을 제안하였다. 플랜트는 시간 지연항을 갖는 2차 모델을 고려하고 목표함수로서 시간 지연항을 갖는 3차의 전달함수를 선택하였다. 필터 함수는 설계사양을 만족시키도록 하는 적절한 목표함수로부터 유도된다. 또한 강인-안정성을 입증하기 위한 강인성을 조사하였다.
