摘要:
针对基于开关表的双三相永磁同步电机直接转矩控制中采用基本电压矢量会在 z1 - z2 子 平面产生大量 6k ± 1( k = 1,3,5,…) 次谐波电流问题,通过引入脉宽调制的思想,对电压矢量进行 修正,并对修正后的中间矢量进行了中心化处理,使其易于硬件实现。对两种直接转矩控制方法进行仿真分析和实验验证,结果表明通过采用修正后的中间矢量进行直接转矩控制可以很好的抑制z1 - z2 子平面的谐波电流,从而减少系统损耗,且控制系统的动静态性能不会受到影响。

Abstract:
 There are a great quantity of 6k ± 1( k = 1,3,5,…) harmonic currents in the z1 -z2 sub-plane when the basic voltage vectors are adopted in switching-table-based direct torque control ( DTC) for dual-three phase permanent magnet synchronous motor ( PMSM) drives. By introducing the principle of pulse width modulation,the voltage vector was modified,and the modified intermediate vector was centralized for simplifying the hardware implementation. Both simulation and experimental results demonstrate that the harmonic currents in the z1 -z2 sub-plane can be suppressed significantly when the modified intermedi-ate vectors are adopted for DTC,so the system losses are reduced. Furthermore,the static and dynamic performances of the control system are not affected.
