Research on MATLAB Simulation of Permanent Magnet Synchronous Motor Vector Control

Abstract：With the advancement of science and technology, permanent magnet synchronous motor (PMSM) has been widely used and developed due to superior performance。 The rapid development of electronic, computer and power electronics has promoted the development of AC electrical drive control, and the development of control theory has provided the theoretical basis for the advanced control strategy of permanent magnet synchronous motor。 Especially in high precision and high reliability control system, permanent magnet synchronous motor has gradually become the mainstream motor。 In addition, China's rare earth resources are relatively rich, which provides a basis for the control of permanent magnet synchronous motor research, making it quickly become the focus of the field of motor control and hot spots。 In order to improve the control performance of permanent magnet synchronous motor control system and achieve the control effect of faster response speed and high precision dynamic and steady state performance, this paper presents the vector control theory of stator minimum current control and id = 0 control。 In this paper, the mathematic model of permanent magnet synchronous motor is established, and the operating characteristics of permanent magnet synchronous motor and the stator minimum current ratio and id = 0 control mechanism are discussed。 The SVPWM control module is established to control the on and off of the inverter power switch, and the two control methods are compared。 The simulation results show that the control effect is good。
