Description
<p>In recent years, there has been an increasing demand for position sensorless control in PMSM drives, and various methods have been studied. Switching noise is a problem in the low-speed sensorless control method that uses the current slope during PWM. Furthermore, another problem is that the inductance does not appear in a sinusoidal distribution owing to magnetic saturation.</p><p>In this paper, we improve the sensorless control method that estimates the position from the current slope during PWM, which is greatly affected by switching. Additionally, we build a multi-layer neural network (NN) that directly estimates the position signals by learning a large amount of current data, and verify the driving results in the low-speed range when the learned NN is incorporated into real-time control.</p>
