| 摘 要： | 对直接转矩控制中电压矢量对电磁转矩的影响进行了详细的理论分析,指出当定子磁链幅值和磁通角变化发生矛盾时,电压矢量对电磁转矩的影响与磁通角(定、转子磁链夹角)大小及定子磁链矢量相对其所在扇区的位置均有关.仿真实验证明了理论分析的正确性,这为解决直接转矩控制的转矩脉动提供了新的思路.

| Abstract: | In this paper the impact of space vector of voltage on electromagnetic torque in direct torque control (DTC) is studied. The conclusion is proposed that when the changes of the magnitude of the stator flux and the flux angle (angle between the stator and the rotor flux) is contradictory, the impact on the torque relates to the magnitude of the flux angle and the position of the stator flux in its sector. The simulation proves the mathematics analysis right. A new way to solve the problem of the ripple of torque in DTC is provided. |
