Modelling and Comparative Study of Ziegler Nichols and Takahashi PID Tuning for Time-Varying Water Temperature

This study presents the comparison of Proportional, Integral and, Derivative (PID) control tuning for time-varying water temperature of Steam Distillation Pilot Plant (SDPP) based on nonlinear modelling. The NARX model was chosen to estimate the transfer function of time-varying water temperature using Pseudo-Random Binary Signal (PRBS) and Multi Sine (M-Sine) Perturbation Input Signal. The NARX model was selected based on the high percentage of fitness. Then, from the model obtained, PID control tuning which are Ziegler Nichols and Takahashi have been implemented. The performance of PID control tuning was depend on the percentage of overshoot, rise time and settling time. The simulation result shows that the fastest rise time and settling time were produced by PRBS with 0.5 band and M-sine with 0.1 band respectively together with a small value of the percentage of overshoot.
