Real Time Implementation of A New CDM-PI Control Scheme in A Conical Tank Liquid Level Maintaining System

Abstract

The work focuses on the development and real time implementation of Coefficient Diagram Method (CDM) based PI (CDM–PI) controller for a Conical Tank Liquid Level Maintaining System (CTLLMS). The process exhibits severe static non- -linear characteristics. Based on the Polynomial approach (CDM), the elements of PI controller are designed and implemented in the conical tank liquid level maintaining control loop. Performance of the CDM-PI controller and its robustness are analyzed and reported.
