Model Structure Determination and Test Input Selection for Identification of Nonlinear Regimes.

摘要

This report describes techniques for model structure estimation and test input design for system identification in nonlinear vehicle regimes. Optimal methods for parameterizing estimation problems are discussed. For those regions where aerodynamic or hydrodynamic force and moment models are not known, the use of splines in approximating unknown nonlinear effects is discussed. Finally, methods for selecting inputs which enhance system identifiability are described. (Author)
