Comparative Study of Fuzzy Controls Applied to a Two-tank System

In this paper three methods of fuzzy control are compared on both their performance in the steady-state and the transient response. This is done by evaluating the performance in terms of raising time, overpass percentage and steady-state error percentage. The first control is based on a Fuzzy Inference System(FIS) Mamdani-type, the second on a Takagi-Sugeno(TS), and the last is a Fuzzy Sliding Mode (FSM) controller [4]. The simulation and experimental results show that an FSM Control has the fastest time response, but its transient response has also the highest overass values an its output ten s to have high-fre
