【摘要】：对于高性能的感应电机矢量控制系统,磁链估计是首先要解决的问题。该文阐述了感应电机带通滤波器补偿电压模型的基本原理,提出了基于该模型的新型定子磁链估计算法。深入分析了带通滤波器极点位置对算法的影响,获得了极点位置与电机运行频率的限制条件。在此基础上引入了定子磁链的自适应相位控制器,增大了滤波器极点的取值范围,提高了算法的动态性能。该文提出的定子磁链估计算法在理论上可彻底解决对反电动势积分时的积分初值与直流漂移问题,在较宽的速度范围内均可获得幅值和相位较为准确的定子磁链,可用于高性能的无速度传感器感应电机矢量控制系统,具有较好的实用性。通过仿真及实验对提出的磁链估计算法进行了验证。
[Abstract]:For the high performance induction motor vector control system, the magnetic chain estimation is the first problem to be solved. This paper describes the basic principle of the compensation voltage model of the induction motor bandpass filter, and presents a new estimation algorithm for the stator flux based on this model. The pole position of the bandpass filter is deeply analyzed and the pole position is analyzed. On this basis, the adaptive phase controller of the stator flux is introduced, which increases the range of the value of the filter poles and improves the dynamic performance of the algorithm. The algorithm of stator flux estimation in this paper can solve the integral initial value and DC drift of the inverse EMF in theory. The stator flux with more accurate amplitude and phase can be obtained in a wide range of speed, and it can be used in the high performance vector control system of speed sensorless induction motor. It has good practicability. The proposed magnetic chain estimation algorithm is verified by simulation and experiment.
