摘要
为了研究异步电机矢量控制中的死区补偿问题,详细分析了逆变器中死区的产生和对输出电压、电流的影响,结合矢量控制中死区时间补偿方法,提出了在异步电机转子磁场定向控制上应用一种基于前馈补偿的死区补偿方法,并对系统应用Matlab/SIMULINK进行了仿真研究。仿真结果表明,该死区补偿策略在矢量控制中取得了良好的补偿效果。
Dead-time compensation in vector-controlled induction motor is investigated. The influence that the dead-time in inverter causes on the output voltage and current is analyzied in detail. In view of deadtime compensation method in vector control, a method based on a feedforward approach is applied on the rotor field-orient control. Furthermore, the simulation of the system on Matlab/SIMULINK is introduced. The result of simulation shows that the dead-time compensation achieves better compensation conclusion in vector control.
