Purpose: The importance of developing automatic speed control systems for hump-shunting diesel locomotives is demonstrated. Using as an example a shunting diesel locomotive of Type TEM7A a mathematical description is provided of electric power transmission as a final controlling element of the automatic control system and of a train as a control object. A flow-chart of the control system is generated and the system’s principle of operation is designed so as to ensure the main requirements to the hump-shunting locomotives are met. The PI speed controller is developed with parameters that provide for a maximum second-order integral accuracy of speed control. Methods: Controller’s optimum values are found using the Monte Carlo simulation. Results: The results of a simulation modeling are presented. Practical significance: The designed control system is found to ensure a smooth transient response and to maintain a given value of speed within the range of 15 km/h when pushing over a hump or at breaking up, providing for an increased shunting capacity of new generation hump yards featuring shunting control systems.
