Abstract：Taking the second-order inertia plus pure hysteresis mathematical model of cement calciner temperature established by step response as the control object,and applying Fuzzy Logic and Simulink toolbox in Matlab to design the fuzzy PID composite control algorithm of calciner outlet temperature,design and implement cement calciner temperature fuzzy controller(FC)based on advantech programmable automation controller(PAC),complete real-time multi-task fuzzy control algorithm software development,and seamlessly connect FC to cement production process distributed control system(DCS)through industrial Ethernet.When the target outlet temperature of the calciner is set at 820℃and 870℃respectively,the FC is static debugging and online testing.The results show that the amount of tail coal given by FC is consistent with the amount of tail coal given by manual in terms of fit and time sequence response.FC can automatically adjust the amount of tail coal,and the temperature control accuracy reaches±2℃,while the average accuracy of artificial temperature control is usually about±10℃.In the selected data sampling time range,the FC intelligent coal feed is reduced compared with the manual coal feed,and the standard coal consumption per ton of clinker is reduced by 2.63%.
