Abstract

DESIGN OF PI CONTROLLER FOR A CONICAL TANK SYSTEM

*G. Pandimadevi M. E. and Dr. V. Selvakumar

ABSTRACT

Conical tanks are widely used in the process industries because of its shape that contributes better drainage for solid mixtures, slurries and viscous liquids. The cone is a well-known system, which is having high non linearity, due to the variation of the area with respect to height. Level control of conical tank is a challenging task due to its non-linear shape and constantly varying cross-section. Thus automatic control of such nonlinear process is a challenging task. To recover the nonlinearity problem dynamics, those sys-tems should be analyzed properly. This paper proposes the tuning of PI controller by Ziegler Nicholas and Cohen coon method. The controllers are designed and compared based on the performance analysis.
