Real time level control of conical tank and comparison of fuzzy and classical pid controller

Abstract

This paper describes about the level control of conical tank by using PID control and fuzzy logic algorithm. Many process industries are equipped with conical tanks because of easy discharge of contents present in it. But level control in the conical tank is most challenging parameter which is to be monitored. This non-linearity can be overcome by different controlling techniques. Conventionally used controller in most of the industries is PID controller. Further the controller is updated with fuzzy logic controller for the enhanced response regarding level control. A result of fuzzy logic controller is compared with conventional PID to analyze the performance in terms of high stability, reliability and robustness.
