IMC Based PID Controller Tuning Method for the Integrating Process with Time Delay |
| 초록 |
A simple IMC-PID controller design technique has been proposed on the basis of the IMC principle for the integrating process with time delay. Further, it is extended for the integrating process with negative and positive zero as well. The proposed PID controller design method is mainly focused on the disturbance rejection, which causes the overshoot in the set-point response. The two-degree-of-freedom (2DOF) control structure has been suggested to eliminate the overshoot in the set-point response. The simulation results show the superiority of the proposed tuning rule over other existing methods, when the controller is tuned to have the same robustness level by evaluating the peak of the maximum sensitivity Ms. The closed loop time constant λ has only one user defined tuning parameter in the proposed method. A guideline has been suggested for the selection of λ for different robustness level by evaluating the Ms value over the wide range of θ/τ ratios. |
