Due to its many advantages, permanent magnet synchronous motor (PMSM) has been widely used in social life and industrial production. In addition, China is vast and rich in mineral resources. Therefore, Waland Motor must conduct in-depth and meticulous research on the control of permanent magnet synchronous motors, so as to apply what it has learned and return knowledge to the world. Vector control and direct torque control are two very mature control strategies, each with its own advantages in daily life and engineering applications. Now, sensorless control has also gradually entered our daily life and become a new trend in the development of permanent magnet synchronous motors.

Development history of permanent magnet synchronous motors,

The development history of permanent magnet synchronous motors (PMSM) began in the early 20th century. With the advancement of electromagnetic material science and power electronics technology, PMSM has been continuously developed and improved in various historical stages.

Early research and development (1900s-1950s):

In the late 19th century and early 20th century, permanent magnet materials such as natural magnets such as magnetite were used in early permanent magnet synchronous motors, but their performance and applications were very limited.

In the 1930s, the emergence of Alnico (aluminum nickel cobalt) alloy greatly increased the energy product of permanent magnets, and permanent magnet synchronous motors began to have more practical applications.

Semiconductor technology leads a new era (1960s-1980s):

In the 1960s, with the emergence of crystalline silicon rectifiers and power transistors, power electronics technology has made rapid progress, which directly promoted the progress of PMSM control technology.

The development of permanent magnet materials is also constantly breaking through. For example, the emergence of rare earth permanent magnet materials has significantly improved the performance of motors.

Fusion of power electronics and computer control (1990s-2000s):

In the 1990s, with the commercial production of high-performance rare earth permanent magnet materials (such as neodymium iron boron NdFeB), the performance of PMSM has made a qualitative leap.

During this period, the application of microprocessors also became popular, and precise control of motors became possible.

The era of intelligence and high efficiency (2000s-present):

In the 21st century, power electronics technology and control algorithms have been further improved, which has optimized the energy efficiency and intelligent control of permanent magnet synchronous motors.

PMSM is widely used in electric vehicles, wind power, industrial automation and other fields, and has become an important part of renewable energy and energy conservation and emission reduction strategies.

International cooperation in technological development (under the background of globalization):

With the development of globalization, scientific research institutions and enterprises in different countries and regions have carried out extensive technical cooperation and exchanges in the field of PMSM, promoting the integration and innovation of technology.

Permanent magnet synchronous motors will continue to develop. With the emergence of new materials and new technologies and the improvement of environmental protection requirements, PMSM will continue to develop in the direction of high efficiency, energy saving, miniaturization and intelligence.

Space vector pulse width modulation (SVPWM) method in vector control. Based on the use of SVPWM method, the traditional sliding mode control algorithm (traditional-SMO) and the sliding mode control algorithm (SMO-dq) in the synchronous rotating coordinate system in the sensorless control technology based on the fundamental wave mathematical model are introduced; and the above three strategies are simulated in MATLAB/Simulink. The simulation results show that the control effect of the motor by the traditional sliding mode control algorithm can be comparable to that of the SVPWM method in vector control, while the control effect of the sliding mode control algorithm in the synchronous rotating coordinate system is slightly worse than the former two. This paper then introduces direct torque control (DTC) and its improved algorithm: direct torque control based on sliding mode control (SMO-DTC), and simulates the above two algorithms in MATLAB/Simulink. The results show that the improved algorithm can improve the speed regulation performance and reduce torque pulsation. As a manufacturer of permanent magnet synchronous motors, our control strategy and the construction of the simulation platform have been completed, providing a solid theoretical foundation for practical applications. Finally, based on the simulation, the SVPWM method is used to complete the design of the hardware circuit with DSP+FPGA as the core, and then the design and writing of the algorithm are completed on this basis, the experimental platform is built and online debugging is carried out. The debugging results show that the system achieves good control performance.
