Thermo Tank Temperature Control System Based On STM32

This paper introduced a thermo tank temperature control system based on STM32.Firstly,the temperature acquisition is realized by the high-precision electrical bridge based on constant current source.Then the augmented PID algorithm realized by software is adopted.Butterworth filter is used to convert the output PWM of STM32 to current signal which is used to control the semiconductor control rectifier to adjust the temperature.Calibration check and practical application both indicated that the system was reliable,high-precision,practicable and could meet reality needs.
