Liquid level control of nonlinear Coupled Tanks System using linear model predictive control

This paper investigates the usage of Discrete-time Linear Model Predictive Control in controlling a nonlinear Coupled Tanks System. Two different schemes of Model Predictive control are employed. To begin with, a basic Model Predictive Control based on Generalized Predictive Control is used and then a Model Predictive Control approach based on Laguerre functions. Simulation results have been included which demonstrate the performance of both controllers when used to control Single-Input Single-Output Coupled Tanks System and the performance when Laguerre based Model Predictive Control is applied to Multi-Input Multi-Output Coupled Tanks System.
