[Abstract]:China is a rare earth country, permanent magnet motor has unique advantages. The permanent magnet motor has obvious performance advantage, but the traditional motor control system is in the western control for a long time. Therefore, it is of great significance to study the integrated control system of the external rotor permanent magnet motor, which is helpful for China to become a manufacturing power. Based on the provincial research project (2015031008-2), a control system of external rotor permanent magnet motor is designed in this paper. The electromagnetic field distribution of external rotor permanent magnet motor is analyzed and its model is established to analyze the transient and static performance of external rotor permanent magnet motor. The direct torque control strategy model based on MATLAB is established, and a fuzzy SVPWM-DTC control strategy is used to simulate and verify, and the outer rotor permanent magnet motor drive plate is made. The DSP floating-point motor control chip TMS320F28335 is used as the core controller to complete the development of the hardware platform. According to the hardware circuit, the related control software is compiled under the CCS integrated compiling environment. Firstly, the physical model of the outer rotor permanent magnet motor is constructed, and the physical structure parameters and performance analysis of the outer rotor permanent magnet motor are studied by using Ansoft/RMxprt software. The two dimensional electromagnetic field of the outer rotor permanent magnet motor is simulated and analyzed. The results show that the performance of the external rotor permanent magnet motor is reasonable. Secondly, in order to construct the mathematical model of the outer rotor permanent magnet motor, the DQ shaft system is selected by comparing the three commonly used coordinate systems, and the direct torque control principle and system construction of the permanent magnet synchronous motor are introduced, as well as several important components. The rationality of the mathematical model is verified and the theoretical support for the control strategy is provided. Thirdly, based on the above model, a fuzzy SVPWM-DTC system model and traditional DTC system model are established based on rotational speed fuzzy PID and SVPWM-DTC system, and the simulation results are compared and analyzed. The simulation results show that the control algorithm of fuzzy SVPWM-DTC outer rotor permanent magnet motor has a good effect on restraining electromagnetic torque and stator flux ripple, and achieves the desired effect. Finally, the external rotor permanent magnet motor control system with TMS320F28335 as the core is developed, and the power inverter module is designed with the IR2136 power driver chip and the DSP28335 built-in module, and the peripheral circuit is designed. The PCB board is made and the power inverter module is welded. The optocoupler isolation circuit is set up to improve the anti-interference ability. The software program of the control system is written under the CCS environment combined with the hardware circuit to complete the design of the duty cycle of the trigger module.
