Some dynamic airframe stability considerations in the control problem

TL;DRAbstract

The dynamic stability analysis of the airframe for consideration in the control problem was made considering six degrees of freedom. The intention was to explore a method and determine the extent that such a scheme could be used in a system known to be non-linear at larger disturbances. It was determined that a very workable system exists whereby differential equations may be simply converted into block diagrams and vice versa. The system is workable for various flight conditions. It can also handle disturbances up to one tenth radian in most cases but is restricted to linear approximations. The system is compatible to any multi-loop control problem and is not restricted to airframe control. A standardized form now exists upon which multi-loop compensation theory research may be conducted using either basic hardware or differential equations as the basic system. The graduate work, for which this thesis is a partial requirement, was performed while the author was attending the U.S. Nava
