ABSTRACT:
Method and apparatus are provided for a Fly-By-Wire (FBW) Control System governing loop-gain (GH) for digital signal processing (DSP) compensation, and with analog compensation, both with and without pilot-input affects, so that aircraft FBW control provides high-fidelity pitch, roll, and yaw axis performance comparable to the 0% Step-Response-Overshoot (SRO) results achieved with open-loop pilot-input only, using conventional controls. The method and apparatus include true modeling of "active" pilot input, with frequency-domain transmission of time-delay times single pole response, as easily calibrated against a step disturbance to the loop-gain, GH, of interest. Both time-delay and single-pole response are given an operating range, applicable from very quick to relatively slow or tired pilots, where out-of-range pilot slowness eventually degrades the fidelity of the pitch, roll and yaw axis performance, albeit in a continuously predictable manner.
