摘要
设计了一种基于单片机的直流无刷电机驱动控制系统。以STC89C52为控制芯片,IR2130为前级驱动芯片,通过分立元件MOS管搭建三相逆变桥进行功率放大。为了实现闭环控制,安装光电编码盘进行实时测量电机转速,通过PID控制算法改善系统的稳定性。实验结果表明:该驱动及控制电路功耗小,电机运行平稳,噪声小,转矩波动小,效率高。
A brushless direct current motor （BLDCM） drive control system based on single chip was designed. STC89C52 was taken as control chip, and IR2130 was taken as the pre-drive chip. A three-phase inverter bridge power am- plifier was built with discrete components MOS transistors. In order to achieve closed-loop control of BLDCM, the photoelec- tric encoder disk was installed to measure the real-time speed. The system stability was improved through PID control algo- rithm. Experimental results show that the power consumption of the drive and control circuit is low, and the motor has smooth operation, low noise, small torque ripple and high efficiency.
