摘要
分析了深度弱磁区域中电流矢量控制的稳定性问题,提出了一种新的关于永磁同步电机(PMSM)的最大转矩电压比(MTPV)弱磁控制策略,以提高系统的稳定性,增加最大转矩时更宽的调速范围,确保不同运行区域之间的平滑转换。通过MATLAB/Simulink仿真,验证了理论分析的正确性,表明使用新方案时PMSM可运行在1:4的速度范围内而没有任何电流振荡和不稳定性问题。
Stability problem of PMSM current vector control in depth flux-weakening area was analyzed,and a new flux-weakening control scheme in the MTPV of PMSM was proposed,which significantly improved stability and increased speed range while maintaining maximum possible torque capability with smooth transition between different operation regions.Through MATLAB/Simulink simulation,the correctness of the theoretical analysis was verified;it was shown that PMSM could operate in the speed ratio of 1：4 without any current oscillation and instability with the new scheme.
