Design of optimal P.I.D controller for unknwon long time delayed system

시간지연이 큰 미지의 시스템에 대한 최적 P.I.D 제어기 설계

This paper presents an off-line P.I.D parameter estimation method during normal operation in power plant. The process parameters are estimated using the recursive least square method. The controller parameters are estimated on the basis of desired characteristics of the dynamic model of the closed-loop control.
