Auto-tuning Smith-Predictive control of three-tanks system based on model Reference Adaptive System

Abstract

This paper presents an Auto-tuning Smith-Predictive Proportional + Integral + Derivative (PID) controller based on Model Reference Adaptive System (MRAS). The Model Reference Adaptive Control employs the MIT rule to set the PID controller parameters on line. Smith-Predictive Control (SPC) is implied to predict the behavior of the system for presented time-delay system. Combination of the adaptive techniques and smith-predictive PID controller results, compared with classical smith-predictive PID which is tuned via Ziegler-Nichols (Z-N) method.
