Title

Development Of Surrogate Models For An Aircraft Synchronous Generator

Abstract

A statistically-based process is under development for validation of computational simulations with experimental data. The focus of this investigation is the development of surrogate models for simulations of an electrical generator model. Several input design variables were selected as candidates for the response of power quality. Designed experiments and advanced statistical analyses were used to screen insignificant factors and develop several surrogate models. Several candidate designs for surrogate models were statistically analyzed for predictive power. Modern Design of Experiments was used to develop Central Composite Designs as well as 2nd-order and 3rd-order Optimal Response Surfaces and compare to standard engineering parametric designs. Sample sizes are statistically controlled for Type I and Type II risk for the Optimal Response Surface designs. Validations are performed for all the design surrogate models and it is determined that only the 3rd-order Optimal Response Surface surrogate accurately reflects the calibration data and predicts the validation data from the original model within acceptable precision and risk bounds.
