Application of fuzzy controller in drum water-level control

Conventional Proportional Integral Derivative (PID) control is often used in present industrial field. Because the control parameters are fixed, the tuning results are difficult to meet the demands and the system is unstable or even out of control. In order to solve these problems, fuzzy control technique is presented to meet the demands of intelligent controlling. In this paper, Matlab is used to confirm that the fuzzy control system has good adaptability and anti-jamming capability. Thus, it is proved that the control methods is successful, meanwhile, it is valid for the problems about analyzing and applying for boiler water-level control.
