Abstract：
This text regard industry boiler water temperature control system as the background, aiming at current the actual control in engineering lack heoretically，putting forward a set of processes that according to intelligence gauge control system.
The boiler equipments is a complicated control object, main input to change the deal is to carries, the boiler water supply, fuel measures and reduce the hot water and send the breeze with lead breeze etc.;It is main to output to change the deal is a vapor a water level, steam pressure, boiler to take to press, excess air etc..Because the importation changes the deal change with exportation the deal mutually connection, if the steam carries the occurrence changes, will cause the vapor a water level, steam pressure necessarily with over the variety of the hot steam temperature.So say that the boiler is a control for much inputting, much outputting and mutually connection object,, this control system from carry control with burn to control the sub- system composing.The control system passes the fuel that regulate provides in to measure to organizes with the reasonable the inside of burns, increasing the movement efficiency of the boiler.Aim at to regulate the object differently, distinguish to design the different the controller of PID, improve the whole control result of the control system.
Keywords：Boiler water temperature control, process control, PID, intelligence gauge
