摘要
在对无刷直流电机的SVPWM控制算法进行研究的基础上,基于STM32的硬件平台设计了正弦波驱动无刷直流电机的控制系统,应用PI控制算法实现转速闭环,应用电流截止负反馈原理实现过流保护。通过实验表明,所设计的无刷直流电机正弦波控制系统能够有效减小无刷直流电机的转矩脉动,提高其运行效率。该系统主要基于霍尔传感器提供转子位置信息,成本较低,结构简单,控制方便,具有一定的实用价值。
The SVPWM control method of BLDCM was analyzed,and the SVPWM algorithm was designed based on the hardware platform of STM32. At the same time,the PI control algorithm was applied to realize the closed loop speed,and the current cut-off negative feedback principle was applied to realize the overcurrent protection. Experiments show that the design of the BLDCM sinusoidal control system can effectively reduce the torque ripple of BLDCM and improve its efficiency. The system is mainly based on Hall sensor to provide rotor position information,low cost,simple structure,convenient control,and has certain practical value.
