20050278085, Dec 15, 2005

Filed:

Oct 10, 2003

Appl. No.:

10/683518

Inventors:

Edward Warkomski - Tucson AZ, US
Keith Myers - Tucson AZ, US

International Classification:

B64C001/00

US Classification:

701006000, 701003000

Abstract:

A control system includes a rate-damping loop that uses a calculated angle-of-attack error to non-linearly scale a rate-feedback signal so that at lower angle-of-attack (AOA) error values, an acceleration feedback term plays a greater role in pitch compensation, while at greater angle-of-attack error values, a rate-feedback term plays a greater role in the pitch compensation. In some embodiments, a control system and method of controlling an angle-of-attack of a moving body are provided. A signal representing an angle-of-attack error is non-linearly combined with a signal representing a rate-of-change of an estimated angle-of-attack to generate a non-linear rate-damping signal. The non-linear rate-damping signal is subtracted from the signal representing the angle-of-attack error to generate a signal to control one or more elements of the moving body.

Abstract:

A control system includes a rate-damping loop that uses a motion parameter error (heading pitch, heading yaw, attitude pitch, attitude yaw, and attitude roll) to non-linearly scale a rate-feedback signal so that at lower motion parameter error values, an acceleration feedback term plays a greater role in pitch compensation, while at greater motion parameter error values, a rate-feedback term plays a greater role in the pitch compensation. In some embodiments, a control system and method of controlling a motion parameter of a moving body are provided. A signal representing a motion parameter error is non-linearly combined with a signal representing a rate-of-change of a motion parameter (or body angle) to generate a non-linear rate-damping signal. The non-linear rate-damping signal is subtracted from the signal representing the motion parameter error to generate a signal to control one or more elements of the moving body.
