Abstract

In this talk, aircraft system identification and control will be presented. Aircraft system identification is the process of determining
an adequate mathematical model of aircraft system, with unknown aerodynamic parameters which have to be determined from measured flight data. The accurate knowledge of aerodynamic parameters is very essential for controlling the aircraft system dynamics. In my presentation, the following parameter estimation problems related to aircraft systems will be discussed.

  1. Calibration of aircraft flow angles in airdata system using sensor fusion approach.

  2. Aircraft aerodynamic parameter estimation from noisy data using adaptive nonlinear filter.

  3. Identification of aerodynamic derivatives and structural modes of a flexible aircraft.


Brief outline on my research contributions in the area of stability analysis will also be presented. Finally, the presentation will be
concluded with glimpse of my future research plan and teaching interest.
