Fuzzy Logic Controller Design for Tank Level Control.

In this paper, a fuzzy controller is designed based on operating mode knowledge and it is implemented in a tank level control system. The mathematical model of the plant is experimentally obtained. An important feature of the plant is its nonlinearity. To control the level of water in the tank over the whole range, one must use three tuning parameters pairs for the PI controller that work around three different operating points. The design of a fuzzy controller that uses the plant information works within the whole range, making it more suitable for this level control. [ABSTRACT FROM AUTHOR]
