1200 degrees Kev Tsim PID Program Qhov Kub Tswj Lub Thawv Hlau Hom Hluav Taws Xob Hluav Taws Xob

Tsim ib daim PID program los tswj qhov kub ntawm 1200℃chav kuaj lub thawv {}}} Hom hluav taws xob kom sov. Tus yuam sij rau kev txhim kho lub PID cov kev pabcuam kub thiab txias rau 1200℃box {}}} hom hluav taws xob rauv lus dag. Tom qab ua tiav thermocouple calibration thiab txias-}}}}}} Cov kauj ruam yog los daws cov lus teb uas tsis muaj qhov cuam tshuam rau qhov kub. Thaum qhov kub nce siab tshaj li 600 degree, cov khoom muaj zog hluav taws xob ntawm cov khoom siv hluav taws xob hloov pauv tau zoo, ua rau muaj qhov tseem ceeb txav hauv cov pa pid txwm muaj. Peb tau txais ib ntu ntu ntu hloov kho, faib cov kev nkhaus cua kub hauv peb txoj kev tswj hwm: qhov ntsuas kub (0-300-800 degree), thiab kub (800-1200 degree).

Nyob rau hauv lub algorithm kev siv, kev tswj hwm fuzzy yog qhia kom muaj kev pab PID. Thaum lub ntsuas cua kub ntsuas pom tias cov teeb cua kub tshaj qhov teeb tsa qhov teeb tsa los ntawm 15%, lub kaw lus cia li hloov pauv hom, dynamically hloov p, i, thiab d coeffients siv kev ua tswv cuab ua haujlwm. Kev sim cov ntaub ntawv qhia tau hais tias qhov kev tswj hwm no yuav tswj tau overshoot nyob rau hauv lub siab {degree, txhim kho ruaj khov los ntawm 40% piv rau cov khoom sib tw pid algorithms.

I. Cov kev xav tau thiab cov hom phiaj kub thiab kub

Cov ntsiab lus tseem ceeb rau chav kuaj kab ke (feem ntau}} {} Kev ywj pheej rauv (1200
Cov hom phiaj tseem ceeb:

Hom phiaj kub: Chav tsev kub txog 1200℃(kho);

Ntsuas qhov ntsuas kub: tsawg dua lossis sib npaug ± 1℃(tuav theem);

Kev Tshawb Fawb Kev Ceev: Tsis muaj qhov tseem ceeb overshoot thaum lub sijhawm ua cua sov (tsawg dua lossis sib npaug) degree), thiab rov qab mus rau kom muaj kev ruaj khov hauv 30 vib nas this tom qab txias / cuam tshuam.

Ii. Kev xaiv kho vajtse (cov hauv paus ntawm qhov ntsuas kub)

PID kub kev tswj xyuas yuav tsum muaj lub voj kaw ntawm "Ntsuas ntsuas kub}}}-}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}}} Cov khoom kho vajtse yog qhov tseem ceeb thiab yuav tsum tau tshaj nrog kev kub siab-} qhov kub thiab txias scenarios txog 1200 degree:

Kev ntsuas huab cua sov: tiv taus kub siab tshaj 1200 degree, muaj qhov tseeb thiab cov lus teb sai; zam kev cuam tshuam rau lub cim. S - Hom Thermocouple (Platinum {3} {} {} Cov xov tooj (0,600}

Temperature control core: supports PID algorithm, AD sampling (for thermocouples), PWM output (for heating control), and strong anti-interference capabilities. StM32 MCU (xws li StM32F103) lossis mob siab rau qhov kub thiab txias tswj plc (xws li Siemens S7-1200, Haum rau Kev Muaj kev lag luam science).

Cua kub tua: kho cov hluav taws xob cua sov (tsis txhob nquag ntawm - tawm ntawm rauv taws cua sov (xws li Silicon Pa pas dej thiab cov hlau hluav taws xob ua haujlwm). Cov khoom - Xeev Ribays (SSRS, xws li DC lub cim (piv txwv li, 50ms lub voj voog, 20ms lub voj voog kos voj voog).

Cua Sov Element: Ruaj Ntseg Ntawm 1200 Qib, Nrog Lub Zog Sib Xws Lub Rooj Kub Kub (piv txwv li 10 - 5kw). Silicon carbon power (haum rau qhov kub ntawm 1000℃thiab 1400 degree, tiv taus rau qhov kub thiab muaj sib luag nrog 1200 degree, tus nqi qis).

Ntu kev cuam tshuam: lim (thermocouple kev cuam tshuam rau kev cuam tshuam), kub dissipation (thiab tswb (ovraphontroller). Tsawg {-}}}}}}}}}}}}}}}}}} lim lim (RC lim kom tshem tawm siab- zaus cuam tshuam); Tshav kub dab dej (SSR); Buzzer + Relay (Ovovemperature Cua Sov Txiav Tawm).

III. PID Qhov Kub Tswj Core Algorithm Tsim

PID (sib npaug - sib xyaw - derivative Kub (kev hloov pauv hloov tau ruaj khov. " Tus qauv mis tseem yog:
Tso zis lub zog u (t)=kp × E (t)
Qhov twg: e (t)=Toard} Lub Hom Phiaj Kub T_Set- qhov tseeb kub t_act); KP (sib npaug coefficient), ki (kev sib xyaw ua ke coefficient), thiab KD (coefficient) yog cov tsis sib xws.
