Modelling and Performance Evaluation of Self-tuning FuzzyPID Controller for Hydro Distillation Process

Abstract

This paper presents the modelling and the performance comparison between self-tuning FuzzyPID and self-tuning FuzzyPI controller for compact hydro distillation process that have been implemented via simulation. The actual process has been modelled by First-Order-Plus-Dead-Time model (FOPDT) approximation. The performance of each controller has been evaluated and analysed under several tests that include setpoint and robustness test. The transient response criteria are used to determine the controller performance that was based on rise time, settling time and percentage of overshoot. Based on the simulation result, it showed that self-tuning FuzzyPID with MF7 can conquer all the transient response criteria's. The self-tuning FuzzyPID-MF7 produced low percentage of overshoot and gave shortest time for rise time and settling time among other controllers.
