Abstract:
A method for generating an output at a selected time of a current batch run to control a batch run variable, the batch run extending over a time period and having a desired process value profile, the method comprising:obtaining a deviation history value set for a preceding batch run, the deviation history value set representing a deviation between the batch run variable and the desired process value profile at selected time intervals during the preceding batch run; obtaining an output history value set for the preceding batch run, the output history value set representing the outputs that were provided at selected time intervals during the preceding batch run; generating a smoothing update as a function of a subset of said preceding output history value set near said selected time in said preceding batch run and as a function of a smoothing convolution window; generating a decoupling update as a function of a subset of said preceding deviation history value set near said selected time in said preceding batch run and as a function of a decoupling convolution window; and generating said output as a function of said smoothing update and said decoupling update.
