Constrained notch filter optimization for a fly-by-wire flight control system

摘要

Alenia Aeronautica S.p.A. developed high skills in Notch Filter design and assessment processes. A fundamental step was taken in the integration of existing software and procedures with a new tool that allows Notch Filter optimization, enhanced with an extra feature for the high-frequency Open Loop Frequency Response Function calculation. The Notch Filter design is based on a constrained optimization routine, which processes data provided by a mathematical and experimental model describing the aircraft coupled flight dynamics and the interaction between the flight control system and the structural dynamics.
