Small coal-fired boiler superheated steam temperature control system designIn coal-fired boiler superheated steam temperature， is an important control Boiler superheated steam temperature is one of the important indexes， the quality of superheated steam temperature is higher， may cause overheating steam conduit damages， The superheated steam temperature is too low， inside can reduce So in the boiler superheated steam temperature， must remain stable at specified Introduces fuzzy PID control in small coal-fired boiler superheat vapor temperature， and the application of this method to control the coal boiler superheated steam temperature， boiler superheat vapor temperature even in a larger extent disturbance to remain Fuzzy control algorithm relies on the mathematical model of the object， the algorithm is simple， easy to realize and interference and object model has strong adaptability time-varying， it can output the size deviation according to automatically adjust to a given value Fuzzy control performance， the equivalent of PD control steady precision， lower PID controller to join system， when the system in large deviation adopts the fuzzy control， within range in small deviation adopts PID Simulation results show that by using this method， the boiler superheated steam temperature control system， control of high control accuracy， high steady
