Abstract
A method of modeling a nonlinear component includes providing a physical model for modeling a characteristic of the nonlinear component defined by a physical expression having a physical nonlinear function depending on variables and parameters of the nonlinear component; determining performance data for the characteristic; extracting global parameter values for the parameters based on the performance data; extracting local parameter values for the selected parameter, while keeping fixed the extracted global parameter values for the remaining parameters, based on the performance data corresponding to the characteristic using the physical expression; training an ANN function from the extracted local parameter values for the selected parameter depending on a variable; and determining a hybrid model for modeling the characteristic of the nonlinear component defined by a modified physical expression including the physical nonlinear function, the remaining parameters, and the trained ANN function depending on the variable in place of the selected parameter.
