Firstly, the control requirements of the practical ultra-high speed permanent magnet synchronous motor are analyzed in detail, and the performance index of the drive control system is given. On this basis, the overall design scheme of the system based on the master-slave control mode of DSP FPGA is proposed. In order to better meet the control requirements, IGBT power switch devices with switching frequency above 50kHz are selected, and the detailed analysis and reasonable selection of other core devices of the system are completed. Secondly, the hardware circuit of the drive control system of the ultra-high speed permanent magnet synchronous motor is designed in detail by using the modular design idea, including the hardware circuit of the main control system and the hardware circuit of the drive system.

Then, the software design of the drive control system of super high speed permanent magnet synchronous motor is completed. This paper describes the overall design of the system, and adopts the idea of modular software design, designs each module, including speed estimation module, speed control module PWM cycle interrupt control module and SVPWM software implementation module AD sampling control module. Fault interrupt processing module, etc. In order to ensure the feasibility of the speed control strategy of super high speed permanent magnet synchronous motor, the speed sensorless direct torque control strategy and the weak magnetic field control strategy are designed in the speed control module. The simulation results verify the feasibility of the control strategy. Finally, the modularization debugging of the hardware and software of the drive control system of the ultra-high speed permanent magnet synchronous motor is completed, and the speed control of the actual motor based on the speed sensor is realized, which verifies the validity and rationality of the design of the drive control system.
