The task of synthesis of the control system of the traction electric drive of alternating current is an integral part of the general task of creation of optimum control system of vehicles that provides performance of the schedule according to the set quality criterion. The purpose of this work is to develop mathematical models for the synthesis of AC control system using vector control algorithm, synthesis of controls and research of their models, obtaining qualitative characteristics of the control system in the simulation process using MATLAB package. The issues of development and research of models for the synthesis of control systems for AC electric drive of an alternating current of a diesel train are considered. A review of literary sources on a given topic and an analysis of existing approaches to solving the most common problems in this area are carried out. Modern options using vector control algorithms are considered. Mathematical models are constructed, modeling of their functioning is carried out. The obtained analytical relations that can be used to develop the structure of the automatic control system of the electric drive of the diesel train and calculate its parameters when specifying a certain criterion taking into account a certain workload of the train. Control laws have been synthesized that provide stable acceleration of a diesel train at various points of the traction characteristic, while the requirements for the accuracy of bringing the control object to a given point in the phase space and the quality of transient processes are fulfilledDownloads
