| Abstract: | To solve the problem of high labor intensity and low accuracy of temperature control in the application of artificial temperature control in the existing heating stage,an automatic temperature control system based on AT89C51 is designed. An executing method for the system design,including temperature measurement, temperature automatic compensate of the cold junction of the thermocouple, algorithm for gearshift integral PID control and parameter self-setting are proposed.It is proved from experiments and practical application that the system possesses high tracking accuracy and stability and can satisfy the demands for the temperature control of heating stage. |
