A control system for the landing gear is described in terms of complex dynamic stiffness. An analysis of the shimmy boundaries using values of complex dynamic stiffness and taking into account the maximum possible perturbations permits finding the necessary parameters of the control system (such as dry friction) for the prevention of shimmy at low amplitudes. The universal description of the control system in terms of complex dynamic stiffness, easy and convenient analysis, and the possibility of analytic estimation and experimental determination of complex dynamic stiffness are indicative of practicability of this canonical description
