一种基于图像跟踪的低凸极比电机高精度初始位置估计方法

In sensorless control of permanent magnet synchronous motor drives, initial rotor position detection is critical to ensure smooth start-up operation. However, extracting initial position information for machines with ultra-low saliency ratios is challenging. To address this issue, this article proposes an estimation method for rotor position using image tracking based on high-frequency rotating vo...
