제목 Design of Robust PID Controller for the Unstable Dead Time Dominant Processes
초록 The modified IMC filter has been proposed for the open-loop dead time dominant unstable processes. Based on the proposed filter the PID tuning rule has been derived for the FODUP and SODUP models. The result of the searching of the filter structure for the IMC-PID controller design clearly exhibit that the critically damped filter doesn’t gives satisfactory response for the dead time dominant unstable processes. This happens due to the less integral action and performance can be improved by improving integral action. The simulation studies show that the proposed design method provides better disturbance rejection and setpoint performance. The robustness for the parametric uncertainty of the controller is evaluated theoretically by Kharitonov’s theorem and multiplicative uncertainty bound has been suggested based on norm-bound uncertainty principle.
