Description
P1=C1×dT1/dt+C2×(T_target−T1)+P1now (1)
ここで、C1及びC2は所定の制御ゲインであり、P1nowは現在の投入電力である。ステップS205において、制御部371は、発熱チップ140及び発熱チップ240に、電力P1を投入する。その後、処理はステップS209に進む。
P2=C1×dT2/dt+C2×(T_target−T2)+P2now (2)
ここで、P2nowは現在の投入電力である。ステップS208において、制御部371は、発熱チップ140及び発熱チップ240に電力P2を投入する。その後、処理はステップS209に進む。このように、第1の温度T1と第2の温度T2とのうち、低い方の温度を基準として、フィードバック制御するように第1の電極部100及び第2の電極部200に投入する電力が決定される。
