英文摘要:In th is paper, a M icro2Con t ro l U n it (MCU ) temperatu re con t ro ller equ ipped w ith digital con t ro ller based on the PID control theory is taking ADuC812 as it s core. The hardw are design m ethod is descr ibed and a ser ies of actual cu rves tested on the tube fu rnace w ith P ID con t ro ller to con t ro l the tem2 peratu re are given. The resu lt show s that th is temperatu re con t ro ller has good effect on temperatu re con t ro l and h igh u t ility values as w ell as it s advan tages are simp le to design it s hardw are, low co st and low pow er con sup t ion and sm all size.
