[Abstract]:Permanent magnet synchronous motor (PMSM) has been widely used in industrial, medical, civil and national defense fields because of its high efficiency, high power density and high reliability. However, the mechanical position sensor installed coaxially with PMSM increases the cost and complexity of the motor system and limits the application of PMSM. In order to solve the problem caused by mechanical position sensor, the sensorless control technology of permanent magnet synchronous motor (PMSM) has been put forward and received wide attention. In this paper, the position sensorless control technology of PMSM based on pulse high frequency voltage signal injection method is studied. Firstly, the development status of PMSM and its control technology is summarized, and the existing PMSM position sensorless control technology is introduced emphatically. After the introduction of relevant technical background, the mathematical model of PMSM is established, and the vector control technology of PMSM is theoretically analyzed and simulated, which lays the foundation of the subsequent research on sensorless position control. Then, according to the mathematical model of permanent magnet synchronous motor, the high frequency signal models at low speed and zero speed are derived. The theoretical analysis and simulation of position sensorless control technology of permanent magnet synchronous motor based on pulse high frequency voltage signal injection method are further completed. Then, a theory of error analysis based on harmonic analysis of pulse high frequency voltage is proposed to solve the system error problem of pulse high frequency voltage signal injection method. Through simulation and numerical analysis, the influence of system parameters on the position estimation error of pulse high frequency voltage signal injection method is obtained. The error analysis theory provides a theoretical basis for the selection and optimization of the control parameters of the system related to the pulse high frequency voltage signal injection method. Finally, a sensorless position sensorless control system based on real-time simulator for permanent magnet synchronous motor (PMSM) is proposed, and the design of hardware and software of the system is introduced. In this system, the theories of vector control, sensorless control and position error analysis of PMSM are experimentally studied, and the correctness of the theoretical analysis and simulation are verified.
