|
This paper proposes a simple approach to design a robust PI controller for an uncertain Coupled Tank system that will guarantee closed loop stability. The Robust Controller design method used here is based on Small Gain theorem. The controller is designed for a coupled tank process which is a good example for an uncertain system.The variable to be controlled is the liquid level in tank2. Inflow into tank1 is considered as the manipulated variable. The performance of the controller is evaluated using Settling time, Rise time and ISE. Simulation is carried out using MATLAB SIMULINK software. |
