| 摘 要： | 在定子磁链定向的同步坐标系下,分析了磁链观测的本质,提出了一种新颖的磁链观测方案.此方案以估计出的位置角为反馈量,分别估计了定子磁链的幅值和相位,解决了电压模型的初始值不准确和积分零漂的问题.仿真证明,该方案具有稳定性好、精度高、对定子电阻变化不敏感等优点,适用于同步、异步电机.

| Abstract: | The essence of flux observing is analyzed in synchronous frame align with stator flux, based on which a new observe scheme is presented. The amplitude and phase is estimated respectively, in stead of vector of flux, with angular and speed as feedback. Drift and initial error are solved absolutely by the scheme. A simulation is carried, the result indicates that this scheme has the merit of steady, precision and robust to the stator resistance. And the scheme is so simple that can be achieved easily in spite of synchronous and asynchronous motor. |
