| 摘要: |
| 提出了具有SVPWM控制和电流调节控制的无位置传感器双绕组无刷直流电机（BLDCM）的起动控制，其中电流调节控制采用两点式比较器控制。该起动控制方法不但能有效控制起动电流大小，而且能改善BLDCM开环起动性能。在Matlab／Simulink环境下，建立双绕组永磁BLDCM起动控制系统的仿真模型。设计了基于DSP2407A的双绕组BLDCM控制电路，并通过软件编程的方式实现了SVPWM的开环起动控制。仿真和实验结果一致，且结果表明了理论分析的正确性。 |

| Abstract: |
| A startup control strategy with SVPWM and current regulation is proposed for the sensorless permanent magnet BLDCM（BrushLess DC Motor） with dual windings. Two-point comparator is used in its current regulation control. It controls the startup current efficiently and improves the open-loop startup performance of BLDCM. The simulation model of startup control system for permanent magnet BLDCM with dual windings is built with Matlab／Simulink software，the control circuit of BLDCM is designed based on DSP2407A chip， and the open-loop control is programmed for SVPWM. The simulative results are consistent with the experimental results，which show the correctness of the proposed control strategy. |
