摘要：

针对电机在低速起动或转速特别低时霍尔输出信号不稳定问题，结合方波控制出力大与矢量控制转矩脉动和噪声小的优点，研究基于霍尔位置传感器的无刷直流电机方波与正弦波复合控制的电机驱动器。在分析霍尔估算原理的基础上，对采用霍尔位置传感器的无刷直流电机矢量控制的起动策略进行研究，分析对比方波控制与正弦波控制在不同负载转矩时的起动性能。仿真与实验表明：为确保电机的平稳起动，根据不同起动要求的场合，可以选择正弦波直接起动和方波切换正弦波起动，该文研究的起动控制策略能有效拓宽无刷直流电机在低速大转矩场合下的应用。

Abstract: To solve the problem of instability of Hall signal outputting when the motor is started at a low speed or operating at a very low speed, combining with the advantages of great output under square wave control and small torque ripple and low noise under vector control, a motor driver for square wave and sine wave controlled brushless DC motor based on Hall position sensor is designed. On the basis of analyzing the principle of Hall estimation, the starting strategy of vector control based brushless DC motor applying Hall position sensor is studied and the starting performances of square wave and sine wave controlled brushless DC motor under different load torques are compared. The simulation and experiment show that to ensure the starting stability of motor, direct sine wave starting and square wave and sine wave switching starting can be chosen according to the starting requirements under different circumstances. The starting control strategy researched in this paper has widely extended the application of brushless DC motor under low-speed and high-torque conditions.
