Application of a reference train model in an automatic control system of freight-train speed

Abstract

One method to increase the quality of control of automatic control systems of the freight-train speed is to use a reference train model in an automatic control system to consider the dynamic processes occurring in the train. Based on this information, the system operates so as to fulfill the requirements for control quality of the speed according to a given system of criteria. However, the use of the complex reference model reduces the parameters of the automatic control-system response speed. It is possible to simplify the model to increase the response speed, thereby decreasing the order of the system of the differential equations describing the train as the object of control. Surveys that have been carried out made it possible to find the admissible degree of simplification of the model that does not cause a significant decrease in the accuracy of calculations.
