摘要
针对电压模型在低速区存在的缺陷,采用一种改进型电压模型,该模型由电压模型和电流模型有机地组合而成,扩展了电压模型的调速范围。设计了基于改进电压模型的矢量控制系统动态仿真模型,在低速区和高速区改变定子电阻进行动态仿真,并对仿真结果进行分析,仿真结果验证了该方法的正确性、合理性。
In response to the disadvantage of voltage model in the low speed region, an improved voltage model is proposed. The model is composed of voltage model and current model and extends the speed regulating range. The vector control system dynamic simulation model is designed based on the improved voltage model system, and a dynamic simulation is performed in the low-speed area and high-speed area by changing the stator resistance. The simulation results verify the correctness and rationalitv of the method_
