摘要:研究了六相感应电机直接转矩控制的新策略.根据直接转矩控制技术,一个小型(2kW)两极六相感应电机驱动系统在电流数字滞环控制下通过Matlab仿真和实验实测得到证实,理论计算结果与实验结果基本一致.仿真和实验结果表明,电磁转矩和转矩电流在MMF平衡条件下呈线性关系而与负载的大小无关,这种转矩控制策略可使系统具有良好的动态性能.

Simulation and experiment on torque control strategy of six-phase induction machine

Abstract:The novel torque control strategy of a six-phase induction machine is studied.Based on the control method proposed, the system performance with the direct control technique is verified by a developed Matlab simulation model and measurements on a small (2 kW) two-pole, six-phase induction motor drive under digital hysteresis current control.It is shown that the calculated results from theoretical derived equations are in good agreement with measured results.The simulated and measured results show that there is a linear relationship between the torque and torque current when MMF balance is maintained in the motor by the drive controller independent of the load condition.The direct control of the torque has the good dynamic performance for the proposed control strategy.
