Abstract

An off-line scheme is used to identify the parameters of a two-dimensional, aerodynamic airfoil model of a helicopter rotor blade system. The continuous time dynamic equations are initially replaced by equivalent integral equations. These integral equations are then approximated as algebraic equations by using orthonormal Walsh Functions (WF) and a least-squares method (via a Frobenius norm) is used to identify the model parameters. Simulation results indicate that this scheme is effective. Un cadre hors-ligne est employe pour identifier les parametres d'une conception bi-dimensionelle d'un "airfoil" aerodynamique d'un systeme de lames rotatrices d'helicoptere. Les equations dynamiques qui sont des fonctions continues de temps sont d'abord remplacees par des equations integrales equivalantes. Puis, ces equations integrales sont approches par des equations algebriques en employant les fonctions de Walsh. Enfin, une methode de moindres carres avec norme de Frobenius est utilise pour identifier les parametres du cadre. Les resultats de la simulation indiquent que la methode est efficace.
