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. |
