Self Regulation Fuzzy PID Control of Boiler Steam Drum Water Lebel

The boiler steam drum water level is one kind of nonlinear large time varying and close coupling multi-variable system.This article has established the boiler steam drum water-level control system's foundation,decided fuzzy PID using the self regulating to control the steam drum water level.It carries on the simulation analysis to controller's design,finally indicated that the self regulating fuzzy PID control to improve the steam drum water monitor system's static state and the dynamic characteristic,thus has realized to the boiler steam drum water level best real-time control.
