시간지연을 갖는 적분 시스템의 간단한 PID 제어기 동조법

다국어 초록 (Multilingual Abstract)

Simple tuning methods of PI, PD and PID controller are proposed for an integrating process with time delay. This is based on matching the coefficients of corresponding powers of s in the numerator and that in the denominator of the closed-loop transfer function. For set-point tracking problem, the derived controller is found to be a PD controller which is shown by Lee's tuning rule based on minimizing the performance indexes (ISE, IAE, ITAE) using a real-coded genetic algorithm. A method can be also proposed PI, PID controllers according to tuning parameter lambda(λ) similar to IMC method. Simulation example is given to illustrate the set-point tracking and disturbance rejection performance of the proposed method.
