摘要
在分析驱动器死区效应产生机理的基础上,首先指出死区效应是永磁同步电机(PMSM)产生电流过零钳位及转矩脉动主要原因;其次完成SVPWM控制算法下因死区效应导致的误差电压矢量描述程式推导,给出了基于d-q坐标系下基于电流修正的死区效应补偿方案。最后,通过电流环试验验证了补偿方案的有效性。
Based on the study of the drive mechanisnl of the dead zone effect,this paper analyzed that the stator current zero clamp and motor torque ripple are caused by dead-time effect, and combined SVPWM control algorithm to complete the description of the error voltage vector caused by dead-fime offeet. Based on d-q coordinate system the dead time effect compensation scheme was given under the current correction. Finally, the experiment verifies the validity of the compensation scheme.
