다중루프 PI 제어기의 설계
Design of Multiloop PI Controller
IMC-PID 제어기 tuning법과 최근의 안정도 조건들을 결합하여 다중루프 PI 제어기를 설계하는 방법을 제안하였다. 이 방법은 간단함과 계산에서 유명한 BLT법에 필적하였다. 더구나 0에서 2배까지의 제어기 이득변화에 대하여 robust하였다. 몇몇 모사는 제어성능이 BLT법에 의한 것보다 우수한 것을 보여주었다.
A procedure designing of a multi-loop PI controller, combining the IMC-PID tuning method and recent stability conditions, has been proposed. It competes with the well-known BLT method in simplicity and computation. Furthermore it is robust for the controller gain variations between zero and two times. Some simulations show that its control performances are better than those of the BLT method.
