계수추정법을 이용한 PID 자동동조 제어기 설계

초록

In this paper, a new PID auto-tuning method has been proposed. The system parameters, represented with transfer function, are estimated via least-square method. Limit cycle and limit gain drive equations are used to calculate the PID parameters. Some simulations results have shown that the proposed method works well when it is applied to the twin rotor system.
