Method and device for controlling and regulating of an industrial unit using a closed loop identification phase of its operating parameters

摘要

The method involves carrying out initialization stage in which identification software generates a model used by a linear multi-variable predictive monitor (MVAC). Variations of input variables e.g. industrial unit feed rate (MV1) are validated. Unit responses are generated and parameters are generated. Precision of the model is evaluated, where the software implements the calculation of precision of the parameters from a criterion that decides starting of iteration from generation of parameters when imprecision starts from disruptions of unit operation during the application of variations.
