基于虚拟三次谐波反电动势与高精度补偿的高速无刷直流电机无传感器驱动

For brushless direct current (BLDC) motor applications, one of the most concerning points in the drive system is the commutation error, which will deteriorate the whole system performance, especially in a high-speed range. Unfortunately, the commutation error is hard to be unitedly eliminated since many non-ideal factors will impact the precision of commutations. To remedy this problem and improve...
