Permanent Magnet Synchronous Motor Control System Simulation

- Nov 10, 2017 -

Permanent magnet synchronous motor is widely used in production and life, and its control system has always been the difficulty of this type of motor. Therefore, it is of great theoretical significance to carry out the control system simulation of permanent magnet synchronous motor. Based on the mathematical model of permanent magnet synchronous motor, a vector control system of permanent magnet synchronous motor based on SVPWM is established. The vector control system of permanent magnet synchronous motor is studied by Matlab / Simulink, and the performance of the control system is analyzed. The effectiveness of the simulation method. Papers work for permanent magnet synchronous motor in-depth study provide a theoretical basis.

Over the past decade, with the development of permanent magnet materials, power electronic devices and control technologies, problems in AC motor control have been gradually solved. Because of its small size, light weight, stable magnetic performance, high operating efficiency, small moment of inertia, small torque ripple and high speed operation, etc., in the modern AC servo system, the permanent magnet synchronous motor High-performance machine tool feed, position control, industrial robots, aerospace and other fields have been widely used. With the advent of dedicated digital signal processors (DSPs) suitable for motor control, the advanced control theory and complex control algorithms for servo systems are provided.

Based on the mathematical model of permanent magnet synchronous motor, a vector control system of permanent magnet synchronous motor based on SVPWM is established. The vector control system of permanent magnet synchronous motor is studied by Matlab / Simulink, and the performance of the control system . Combined with the system design and verification requirements, the pre-planning, mid-term design and post-verification of the system can be realized through the simulation software, which will effectively shorten the product development cycle and greatly improve the product development efficiency.
