Title:
【発明の名称】統計的設定点バイアス制御方法および装置
Document Type and Number:
Japanese Patent JP2950513
Kind Code:
B2
Abstract:
A process controller may incorporate statistical computations of the variance in the controlled variable. Statistical measures may then be used to offset the controller set point to maintain the controlled variable distribution in an acceptable specification zone. The statistical measures may be made automatically and continuously thereby obviating human intervention, while producing high quality, though statistically variable, process output. The statistical measures may be calculated specifically or generated by a weighted integration method.
