Design and Development of Model Based Controller for a Spherical Tank

Abstract

Control of process parameters is one of the important problems in process industry. The process considered for modeling
is spherical tank liquid level system. Control of liquid level in a spherical tank is nonlinear due to the variation in the
area of cross section of the level system with change in shape. Nonlinear process control is a difficult task in process
Industries. Spherical tank is a nonlinear system due to its variation in the area of cross section. In this project the
modeling of Spherical tank system is done. The nonlinear parameters are linearised by using the Taylor -series. The
controller is designed using Model Reference Adaptive Controller based on MIT rule. Adaptive Controller for Spherical
tank system is simulated in matlab simulink environment.
