Comparison between MPC and PID control for compact hydro distillation process

Abstract

This paper presents water temperature of a hydro distillation that have been modelled by using linear ARX Modal. Based on the modal obtained, a model predictive controller and PID controller have been developed. Both controller undergone the performance of controller tests that includes set point, set point change and load disturbance. The aim of those three performance tests are to test the robustness among those controllers. In this study, the analyzed via simulation. The criteria of transient responses which are rise time, settling time and percentage of overshoot is robustness among those controllers. In this study, the comparative of the controller performances were evaluated and analyzed via simulation. The criteria of transient responses which are rise time, settling time and percentage of overshoot is chosen to evaluate the robustness of the controller performance. The simulation result shows that the better performance of overall robustness test have been conquered by MPC with compared to PIDCC and PIDZN.
