摘要
在分析单电阻采样母线电流重构电机三相输出电流方法和技术难点的基础上,针对电流采样窗口不足且存在振荡的问题,提出一种延迟电流采样时间避开电流振荡的方案,同时通过电路设计减少电流振荡。基于TMS320F2811控制芯片的电机矢量控制平台进行实验,实验结果证明了该方法的可行性和正确性。
The single shunt current reconstruction method has a limitation because under certain condition the DC-link current pulses becomes too narrow and has oscillation, so that the sampling window is insufficient.For this reason a new method is studied using time-delay sampling and current measurement circuit.The motor vector control platform based on TMS320F2811 digital signal processor（DSP） is implemented.The test show that the method is feasible and correct.
