Model parameters determining method for hybrid physical-mathematical model of piezo-common rail control valve for burner of gas turbine, involves varying model parameter to be determined by mathematical optimization algorithm

摘要

The method involves supplying an input variable to a physical line, and removing real, measurable output variables. The output variables are calculated by the input variable and a model parameter at a hybrid physical-mathematical model. The physical line and the model are connected in a parallel manner. A variable is determined as a sum or integral of a difference between the output variables to individual time points or over a time interval. The model parameter to be determined is varied by a mathematical optimization algorithm, and is identified by global minimum of the former variable.
