Process control methods and apparatus for controlling batch processes including batch heating processes. The present invention includes iterative learning control (ILC) techniques to provide improved run-to-run process control. One method provides a desired temperature profile over the length of a batch time period. This method gathers historical measured value data over the length of a first batch run which can be converted to deviation or error historical data, as well as a historical output history of outputs provided to control the process for the first run.

Why it's free to use
- Filed September 18, 2001. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 18, 2021.
