Using fuzzy logic controller for a two-tank level control system

Abstract EN

This paper presents a fuzzy logic controller for a two-tank level control system, which is a process with a dead time.

The fuzzy controller is a proportional-integral (PI-like) fuzzy controller which is suitable for steady state behavior of the system.

Transient behavior of the system was improved without the need for a derivative action by suitable change in the rule base of the controller.

Simulation results showed the step response of the two-tank level control system when this controller was used to control this plant and the effect of the dead time on the response of the system.
