| Summary: | This study evaluates the effectiveness of transfer function-based control strategies for the Agarwood hydro distillation process. To stimulate the nonlinearity of the system dynamics, pseudo random binary signal (PRBS) and multi-sine (M-Sine) signals were used as perturbation input signals. Using data gathered from the distillation pot, the System Identification tool in Matlab was used to determine the transfer function. The easiest open-loop test that has been executed on a real plant is the Reformulated Tangent Method (RTM). The ProportionalIntegral-Derivative (PID) tuning rules developed by Ziegler Nichols (ZN), Cohen Coon (CC), and Takahashi (Taka) were employed in this work. Analysis of the relative performances of PID-ZN, PID-CC, and PID-Taka was done based on transient reactions including settling time, rising time, and percentage of overshoot. To adjust better result, the value of PID gains was changed using the fine-tuning method. The results of the investigation showed that, in comparison to other tuning rules, the CC tuning strategy generated superior results for PRBS input in terms of faster rising time and settling time as well as a smaller percentage of overshoot. |
