Abstract
The work solves an actual problem related to the development of a mathematical description and creation of models of valve machines, which are of important scientific and practical importance for the study of operating characteristics and the design of new control algorithms. We proposed a solution to the problem of analysis of dynamic processes in a valve electric machine using the Simulink application of the MATLAB environment. We proposed a solution to the problem of analysis of dynamic processes in a valve electric machine using the Simulink application of the MATLAB environment. The created models make it possible to obtain the main characteristics by which the working properties of engines are evaluated: electromechanical, mechanical. The results show that the operation of the valve machine is practically similar to the direct current machine. When building a model of a valve electric machine, control with current feedback and maintaining id = 0 should be carried out. This reduces the deterioration of mechanical, control and energy characteristics in a stable mode of operation. In general, if we compare a valve machine with a direct current machine, then its features are mainly manifested in the stable mode in the form of deterioration of mechanical, control and energy characteristics. As for the dynamics, the simulation results show that the valve machine is practically analogous to the DC machine. Analyzing the model as a whole and using the measuring tools provided by Simulink, it is possible to determine the losses in the motor, calculate the equivalent currents, torques and powers and check the correctness of the motor selection. The results obtained from such a generalized analysis can be extended to different engine operating modes. The proposed model for solving the problem of analysis of dynamic processes in a valve electric machine using the Simulink application of the MATLAB environment is characterized by functionality and the possibility of using the obtained results and the model itself in the design of modern electrical equipment.
