Abstract :
Liquid level in tank is very important for the industries for water treatment, chemical process, oil & gas. The control of liquid level in tank is still very difficult to achieve, because of the non-linearities that the system presents. Model-free controller is then a good solution to overcome the difficulties linked to the finding of the mathematical model of the system. The proposed model-free controller is easy to tune and implement. The performances for this model-free controller are also good enough to make it suitable for industry because there is no need of special knowledge for the tuning of this controller.
