| 摘 要： | 深入分析了传统的基于U-I模型的感应电机定子磁链观测方法的局限性,详细探讨了基于坐标变换的饱和反馈双积分器的补偿原理和相关参数的选取原则.理论分析和仿真结果表明,正确选取反馈通道的限幅阀值,该积分器可以在有效抑制饱和与直流漂移的同时,完全补偿相位和幅值误差.实验结果进一步证明了该方法的可行性、有效性和正确性.

| Abstract: | The limitation of conventional induction motor stator flux observation method based on U-I model was profoundly analyzed.The compensation theory and the relevant parameter selection principle of the saturation feedback double integrators based on coordinate transform were researched in detail.It shows that the saturation and DC drift can be rejected effectively,the phase and amplitude errors can be compensation completely at the same time by the academic analysis and simulation results.The feasibility,availability and validity are approved by the experimental results. |
