Firstly, the temperature acquisition is real- ized by the high-lxecision electrical bridge based on constant current source. Then the augmented PID algorithm realized by software is adopteff But-terworth filter is used to convert the o.aput PWM of STM32 to current signal which is used to control the seniconductor control rectifier to adjust the temrature. Calibration check and practical application both indicated that the system was reliable, high-precision, practicable and could meet reality needs.展开更多
