Research on Vector Control Simulation Based on Field-Road Coupling

Abstract

In vector control simulation, the MATLAB/Simulink model of the permanent magnet synchronous motor cannot fully simulate the inherent characteristics of the motor. It leads to problems such as reduced simulation accuracy and limited applicability of analysis results. In order to solve these problems, this paper designs a joint simulation model. This model is established based on the direct field-circuit coupling equation and the vector control strategy. It can take into account both the analysis of the electromagnetic characteristics of the motor and the analysis of the control circuit. This paper analyzes the speed, current and electromagnetic field distribution under different working conditions, and these simulation results show that the model is feasible.
