Model based Controller Design for Conical Tank System

Abstract

The control of liquid level is mandatory in process industries. But the control of nonlinear process is complex. Many process industries use conical tanks because of its non linear shape which contributes better drainage for solid mixtures, slurries and viscous liquids. So, level control of conical tank presents a challenging task due to its nonlinearity and constantly changing cross-section. The main objective is to implement the suitable controller design for conical tank system to maintain the desired level. In this paper it is proposed to obtain the mathematical modelling of a conical tank system and to design model based controller (Internal Model Control) for controlling the level in it. The controller will be simulated using MATLAB SIMULINK. By using the advanced control scheme it is expected to have better closed loop performance and robustness when compared to PID controller.

Adaptive Pressure Control System Based on the Maximum Correntropy Criterion

“…In [ 6 ], a Reference Model Adaptive Control (MRAC) system was carried out for a conical water tank system, showing its robustness and high performance to randomness, i.e., adapting the model parameters to the parametric variations of the system, such as roughness, temperature, water density, and others. An adaptive PID control by gain scaling was developed in [ 7 ], applied to pressure regulating valves in water distribution networks.…”

Soft Computing Technique and Conventional Controller for Conical Tank Level Control

“…The control of nonlinear [1] systems has been an significant research topic and many approaches have been proposed [2] . In most of the process industries controlling of level, flow, temperature and pressure is a exigent one.…”
