Protection system of AC mine electric locomotive from the emergencies

Development of a system to control the motion of electric transport under conditions of iron-ore mines

“…This process is complicated by the fact that the line of mine electric locomotives manufactured by machine-building enterprises is outdated and far from being perfect [7]. It is the type of electric locomotive and its traction drive that can become an "elevator" that will raise the mine transport to the level of up-to-date automated control systems.…”

“…The process of the model synthesis was carried out in two stages. At the first stage, structural identification was made the meaning of which was to choose the dependence of the input and output variables of the control object without taking into account the values of its parameters [7]. In drawing up the system equations, it is natural to assume that the "locomotive -wagons" system can be represented in a form of a structure consisting of several masses connected by elastic (coupling) and rigid (rails) joints.…”
