“…Equation (13) shows that i αh and i βh are sinusoidal functions, that their amplitudes contain position angle information and that the amplitudes of i αh and i βh are regulated by position angle. In order to obtain the current amplitudes I α and I β , the traditional method is to multiply the values of i αh and i βh by sinω h t and then get the values of I α and I β through a low-pass filter, as shown in Equation (14).…”

“…The high-frequency signal injection method is based on the salient pole effect of the motor, which can effectively estimate the initial rotor position of the permanent magnet synchronous motor. According to the nature of the injection signal, it can be divided into a rotating high-frequency signal injection method [11] and a high-frequency pulse signal injection method [12]; according to the position of the injection signal of the whole motor control system, it can be divided into a high-frequency voltage signal injection method [12][13][14] and a high-frequency current signal injection method [15]. Among these, the representative methods include a voltage pulse vector injection method [16,17] and a high-frequency signal injection method [17,18].…”

“…The inductance of the IPMSM changes according to the rotor position. High frequency voltage or current is injected into the stator to observe the rotor position [12]- [15]. Sometimes, the PWM voltage can also be taken as a kind of high frequency signal [16], [17].…”
