Model Reference Adaptive Controller for Non-Linear Processes

Abstract

This paper presents the application of adaptive controller for three different non-linear processes and analysing the effect of the controller for three systems which are having different levels of non-linearities. The controller chosen is a direct model reference adaptive controller (DMRAC) for adjusting the feed forward gain using MIT rule. The non-linear systems considered are cylindrical tank, conical tank and spherical tank. The model reference adaptive controller is designed and implemented in real time by using LabVIEW. The result shows that model reference adaptive controller shows better results than conventional Proportional Integral (PI) controller.
