This article shows results related to application of impulse signal shapers (ZV, ZVD, EI), applied on reference signal as a feed-forward vibration compensator for pilot commands incorporated with feedback control system (FCS) design for blended-wing-body aircraft (ACFA 2020). The results are nicely indicating ability of connection feed-forward approach for reducing vibration cooperation with active damping. Other goals are study signal shapers design for hard nonlinearities in elevator and ailerons like saturation and rate limiters, induce by finite rates and deflection of servomechanism of control surface. Standard design can't be directly used for higher deflection of elevator and ailerons, because nonlinearities deform shaped command. Two efficient modifications used as alternatives to standard shapers configuration, suggested in the article, permit application of the feed-forward compensation in respect of this setup.
