摘要
提出一种基于定子磁链定向的异步电机无交流电压传感器自然坐标控制策略,降低了系统成本,提高了系统抗扰动能力。针对矢量控制计算量大、编程复杂的问题,采用自然坐标变换,避开三角函数计算,通过有功、无功电流控制实现电机转速和定子磁链的解耦控制。最后,通过实验验证了所提策略的可行性。
A control strategy of alternating current （AC） voltage sensorless based on the stator flux oriented nature co- ordinate controlled induction motor is presented.This strategy decreases the cost and improves the anti-disturbability of the system.Involving triangle functions, the vector control is complicated to be calculated and programed, so the nature coordinate transformation is adopted to avoid triangle functions, by which the decoupling control of the rotor speed and the stator flux are realized.The experimental results verify the feasibility of the proposed strategy.
