Supplemental control for robust flight cruise in turbulent time windows

Turbulence during flight cruise is known to prevail over discrete time windows. The control surface deflections to recover ride quality at these time windows are important, specifically in high speed cruise vehicles. In this paper, we assume that the turbulence is measurable as an impulse of known intensity at a given time instant and, provide simple formulas for the supplemental control impulse minimizing its effect on ride quality. These thumb rules are particularly useful to evaluate the desired ride quality metrics, control magnitudes etc., at the time instances during which the flight cruise is felt with turbulence. In the high speed civil transport type of vehicles, these magnitudes are critical and may be discontinuous with respect to the nominal flight cruise
