Description
● 液体供給用の比例型調整弁52の弁位置は、温度センサ24によって測定される出口温度と、必要な設定点温度とに基づき、PID制御アルゴリズムに従って制御される。設定点温度は、通常は一定値である。
○ m:調整弁52の弁の位置(0〜100%)
○ e:測定温度と設定点温度との間の温度差
○ Kp,Ki,Kd:比例係数、積分係数、微分係数
圧縮空気の調整弁66の弁位置も、PID制御アルゴリズムによって制御される。様々なアルゴリズムを使用することができるが、入力パラメータは、圧力センサ70によって測定される空気圧力と、必要な空気圧力設定点とに基づく。空気圧力設定点は、液体流量計54によって測定される現在の液体流量に依存する。
○ 最小入口ガス条件(一般には必要な液体流量が最小)
○ 標準入口ガス条件(一般には必要な液体流量が標準)
○ 最大入口ガス条件(一般には必要な液体流量が最大)
