MBC – Models Adaptation |
A.A. Moiseev
Possible purpose of MBC – models use is calculation of non – measured values in control systems and invalid measurements doubling.
Both variants of model use require model adaptation: on indirect measurements in the fi rst case and on valid measurement in the second
one. Proposed original adaptation method based on linear controllers use. The last ones stand as numerical solvers of model equations for
adjusted parameters, i.e. in fact as model adapters.
Model values can be used at multi – channel measurements dispersion. The measurement nearest to model value considered as valid
one. It’s possible that adjusted parameter isn’t correct at large deviation of model value. In this case it can be useful to perform preliminary
running and build interpolation dependence of adjusted parameter from some measured factor, for example, load power. Adaptation
schemes were built as examples for pressure and temperature models of gas supply to combustor.
Keywords: combustor, control system, non – measured values, invalid measurements, MBC – model, adaptation, linear controller
