Abstract :
Comprehensive study on control stability analysis before controller design is an indispensable important step for any flight system. In this paper, frequency modal responses and relative input-output controllability are analyzed quantitatively to provide valid instruction for structure improvement. In this project, tilting electric ducted fan (EDF) system is devised for an unmanned tandem ducted fan vehicle to improve the stability and controllability over wind disturbances. Forces and moments of the vehicle are investigated by comprehensive nonlinear modeling. Static thrust experiment has been done for more accurate parameters. Different reference speed of EDFs is considered and studied to evaluate the controllability of different channels.
