6 Simulation vs system identification. that this can be done before the aircraft has been built. In some cases the agreement between the predicted and measured dynamic behavior is unsatisfactory, at least initially, before "tuning," because of the accumulated uncertainties and modeling simplifications. The approach is less suitable for small unmanned air vehicles (UAVs), which often have unique designs that are not similar to any existing database. System identification and simulation modeling can be seen as inverse procedures, as shown in Fig.

4) requires the use of system-identification procedures to extract parameters such as bandwidth and phase delay directly from flight-test frequency-response data. S. fixed-wing aircraft (MIL-STD-1797 Ref. 5) involves using system identification to extract transfer-function models, also referred to as equivalent system models, from flight-test frequency responses. System-identification procedures and example results of handling-qualities and flight-control analyses of rotorcraft and fixed-wing aircraft are presented extensively in this book.

12 An often-cited deficiency of the system-identification approach is that the identified parameters reflect the "lumped" contributions of numerous physical mechanisms. , and roll inertia. The identified stability derivative parameters such as Xu or Mu reflect even more numerous and offsetting contributions. This lumping of aerodynamics and dynamics contributions in a single effective parameter often makes it difficult to track down the individual physical contributions as a means to improve the fidelity of physics-based simulation models.
