Description
R1=V1/I1 (1)
同様に制御部172内の温度算出部173は、第2の電圧V2と、発熱チップ駆動回路174から取得したこのとき流れる第2の電流I2とに基づいて、薄膜抵抗153の抵抗値R2を下記式(2)により算出する。
R2=V2/I2 (2)
T=C1×R+C2 (3)
ここで、C1及びC2は、エネルギ処置具120毎に求められた第1の発熱チップの特性に応じた定数である。定数C1及びC2は、例えばメモリ123に記憶されており、エネルギ処置具120が制御装置170に接続されたときに読み出され、例えば記憶部178に記憶される。温度算出部173は、記憶部178に記憶された定数C1及びC2を読み出して、これを用いて演算を行う。
P=C3×(Top−T)+Pnow (4)
ここで、C3は制御ゲインであり、所定の値が与えられている。Topは目標温度であり、Pnowは現在投入されている電力である。ここでは制御ゲインをC3とする単純な比例制御としているが、より安定した制御を行うために、PID制御を用いてもよい。ここで得られた電力Pを、発熱チップ140とシートヒータ150とに投入する。
V1=(P×R1)0.5 (5)
V2=(P×R2)0.5 (6)
ここで、第1の抵抗値R1と第2の抵抗値R2とは異なる可能性があるので、同じ電力Pを投入するとしても、第1の電圧V1と第2の電圧V2とは異なる可能性がある。
