Stalls and Splines: Current Trends in Flight Testing and Aerodynamic Model Identification

Abstract

Aerodynamic model identification remains essential for simulator operations and control system design and operations. In this paper, state-of-the-art methodologies for aerodynamic model identification and validation are presented, together with a number of novel applications of the identified models that were recently investigated and developed at the Faculty of Aerospace Engineering of Delft University of Technology. In particular, this paper focuses on methodologies for identifying models of aerodynamic stall from flight data, as well as multivariate spline-based aerodynamic model identification methods, together with their applications in flight simulation and advanced flight control.

Practical System Identification and Incremental Control Design for a Subscale Fixed-Wing Aircraft

“…System identification for aircraft is a wide topic, and many branches of the field are discussed in [4][5][6]. Recent advances in aircraft system identification include [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25]. Several methods above use frequency domain identification, which was also studied in [26][27][28][29].…”
