Abstract

This paper presents a method to model the system of controlling the position of the load for the overhead crane, serving the automation of the overhead crane system in practice. Since the control of overhead crane systems for different applications in practice will require different control accuracy, for systems requiring low accuracy, a simple dynamic model can be used. . Therefore, in this paper, the modeling of the overhead crane system is carried out according to the following steps: First of all, the model of the moving position of the trolley, the girder system and the length of lifting and lowering the load is performed, with the equations of three axes of motion according to Newton's 2nd law. Next, approximate approximations are made to simplify the dynamic equations of the system. To check the necessary accuracy of the dynamic equations, the article simulates the operation of the mathematical model, according to the parameters of the miniature overhead crane system. And correct the input gain of the forces acting along the axes to demonstrate the usability of the built mathematical model.
