Abstract：With the further development of science and technology and pay more attention to energy conservation and environmental protection, people have put forward higher requirements in two aspects of the performance and efficiency of the motor. The permanent magnet synchronous motor (PMSM) has been widely used because of its high efficiency, high power factor and high starting torque. Permanent magnet synchronous motor (PMSM) has been widely used in many fields, and its control requirements have also been improved. A lot of high-performance control schemes, such as vector control (FOC) and direct torque control (DTC), have been developed.
This paper analyzes the working principle of permanent magnet synchronous motor, the mathematical model and control strategy. Based on using STMicroelectronics STM32F103 as controller, I designed the permanent magnet synchronous motor vector control system. In this paper, there is a detailed description of the vector control system, which is pided into two parts of hardware and software. The hardware part includes: STM32F103 main control core circuit, three-phase bridge inverter circuit, voltage and current sampling circuit, PWM output circuit, HALL interface circuit; software part includes: initialization program, main program, state machine control program, FOC algorithm control program and PC debugging procedures.
STM32F103 has many advantages as a system master. It has a complete FOC solution, and STMicroelectronics designed a perfect PMSM FOC motor library and ST Motor Control Workbench PC debugging software for its production. In addition, the chip is widely used in the field of motor control because of its good performance and low cost. STM32F103 has rich on-chip resources, include multi-channel timers, multi-channel high-precision AD module, rich communication interface, Hall detection interface, and so on, so that the entire control system circuit design is simplified. The experimental results show that the STM32F103 master control and FOC algorithm can realize the vector control of PMSM.
