Title:
SET POINT CURVE UPDATING METHOD AND SYSTEM, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/039846
Kind Code:
A1
Abstract:
A set point curve updating method and system, and a storage medium. The method comprises: for process control based on a current set point curve, acquiring the actual input value curve of the process control and an error curve between a desired output value and an actual output value (S11); performing interference cancellation as well as inverse operation of the process control on the error curve between the desired output value and the actual output value, obtaining a compensation value curve, superposing the actual input value curve and the compensation value curve, obtaining a current optimization set point curve, and storing the current optimization set point curve as a historical optimization set point curve (S12); and obtaining a next set point curve according to a plurality of historical optimized set point curves the times of storage of which are more recent, replacing the current set point curve with the next set point curve, and obtaining an updated current set point curve (S13). Therefore, the updating accuracy for a set point curve can be improved.
