Hysteresis is a collective name for strongly nonlinear phenomena which occur in engineering, physical and economic systems. The wording 'strongly nonlinear' means that linearization cannot encapsulate the observed effects. In particular, standard linearization techniques are not applicable in the analysis of dynamical systems with hysteresis nonlinearities. Nevertheless, evolution operators of such dynamical systems typically have derivatives at many "important" points, which is enough to develop efficient modifications of gradient methods, linear stability analysis methods, etc. In this paper, we suggest a linearization algorithm for dynamical systems with the Preisach hysteresis operator. We present and justify an algorithm for calculation of the derivative of the Poincare map for scalar equations with a periodic solution of a simple form. We also suggest a version of this algorithm for a general class of non-periodic solutions of multi-dimensional equations with the Preisach nonlinearity.
