The question of parametric identification of a nonlinear model of an electrohydraulic drive of aircraft control systems

Abstract

The paper proposes an approach to the identification of the parameters of the electro-hydraulic drive of the aircraft control systems. A mathematical model of an electro-hydraulic drive is described, which includes a model of an electromechanical converter, a model of a hydraulic amplifier and a model of an executive hydraulic motor with a payload. The method of gradient descent and the method of uniform search are considered as identification methods. The results of identification of the coefficient of consumption of the electrohydraulic drive are given.
