The Bang-Bang Control of Water Tank System Based on Fuzzy Decision

The tank system is a typical industrial system model, which is abstracted from water level system in process industry field. Generally it has the characters of time lags, non-linearity and difficult to build mathematics model etc. For some deviant problems often appeared during the control of the water tank system, this paper adopts fuzzy decision strategy to deal with them. The simulation effects of the fuzzy decision controller show that this controller has the characters of responding quickly, small overshoot and less static errors, and it is practicably and feasible in process industry area.
