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