摘要
从理论上分析了定子磁场定向矢量控制的特点，对几种常见的定子磁链观测方法进行了深入地分析和比较，最后设计出一种基于反馈通道的混合磁链模型观测器，给出模型转换点的选取方法。仿真验证该模型对定子、转子电阻的鲁棒性强，模型转换过程磁链、转矩过渡平滑。
The character of Stator Flux Field Oriented Vector Control system is discussed in this paper, and the usual observation methods of stator flux are analyzed and compared in detail. Finally this paper designed a Hybrid Stator Flux Observation Estimator based on the feedback channel, and presented a method that how to select the transition point. The simulation results prove the designed Estimator has a strong robustness to the stator and rotor resistance, stator flux and torque wansit smoothly during the switching process of the flux observation estimator.
