摘要
双极性驱动有利于BLDCM的伺服控制,可提高低速运行时的稳定性。复杂可编程逻辑器件(CPLD)可实现强大的数字逻辑功能,利用该特性实现了电机双极性驱动逻辑控制,简化了控制芯片的外围设置,同时实现了开关管的死区控制,避免了相桥臂直通。在理论分析和仿真的基础上,完成了电机运动控制器。控制器实验结果与理论分析基本吻合,验证了控制方法的正确性。
Bipolar drive availed to control the brushless DC motor （BLDCM） , and enhanced the stability of the motor at low speed. Complex programmable logic device （CPLD） are good at Boolean calculation, an approach to the implementation of the logic of bipolar drive for BLDC motor hased on CPLD is presented. The peripheral devices of CPU could be simplified. As dead - time was actualized, the short through of phase bridge could be avoided. Finally, the measurements are taken on a motive controller. The experiment results are coincided with the simulation and the theoretical analysis. The feasibility and the correctness of the bipolar drive for BLDCM are verified.
