The calculation model of the dynamic system "combine - face" with uncorrected and corrected feed systems can be represented by the following systems of equations.

Out of a large number of works on the study of the dynamics of shearers, a significant part is devoted to the study of mathematical models of the shearer, in which the dynamic system under consideration is represented by a linear oscillating system with several degrees of freedom, and the action of the face on the drive of the shearer by some moment containing constant and variable components.
