“…Han et al combined the carrier frequency method with pulsating high frequency voltage signal injection to measure the initial position error of the rotor of a surface mounted permanent magnet synchronous motor within 2° [17]. On the basis of pulsating high-frequency signal injection, Mai et alproposed an improved position error signal extraction strategy based on amplitude observer [18]. In the case that speed reversal or load step cannot guarantee the accuracy of rotor position measurement, the method based on adaptive observer position error signal extraction is adopted, and the rotor position measurement error is about 3°.…”

Permanent magnet synchronous motor (PMSM) has the advantages of high torque/inertia ratio, high power factor, fast dynamic response speed and high reliability, and has been widely used in various high-precision AC drive systems. Incremental encoders are usually used to achieve high precision position feedback information for permanent magnet synchronous motors. The use of sensors leads to cost increase, volume increase and reliability reduction. Therefore, the sensorless measurement technology of permanent magnet synchronous motor is more and more concerned and applied by industry and research fields. In this paper, the related literature of sensorless measurement technology of permanent magnet synchronous motor is investigated, and the sensorless measurement technology is comprehensively reviewed. This paper introduces in detail the basic principle of various sensorless measuring techniques, the accuracy of position measurement and the application in the type of permanent magnet synchronous motor. In this paper, the concept of speed pole logarithm ratio is proposed to divide the speed region, and the initial rotor position, low speed and medium speed non-inductive measurement methods are described and compared. Finally, the non-inductive measurement accuracy of permanent magnet synchronous motor is summarized.

“…This method obtains rotor position information accurately by applying HF excitation signals and utilizing motor saliency effect. The HF injection method can be divided into three categories: HF rotating signal injection method [12], HF pulsating signal injection method [13], and HF square wave signal injection method [14]. The implementation process of HF pulsating signal injection method is relatively simple, but there are problems such as long convergence time and insufficient stability [15,16].…”

“…The current demodulation process is still relatively complex. In [24], an improved self-adjusting frame amplitude convergence (SFAC) current demodulation method is proposed, which extends the speed applicability of the SFAC method from zero speed zone to non-zero speed zone, simplifying the current demodulation process to some extent, but additional demodulation signals need to be constructed to complete the demodulation. In [25], an estimated position feedback current demodulation method is proposed to eliminate the effect of rotational speed on position error, but it still needs to construct two demodulation signals to complete the positive and negative sequence HF current separation and position error compensation.…”

To address the issues of complex current demodulation, large rotor position estimation error, and position estimation error varying with speed in the high-frequency (HF) rotating voltage injection (HRVI) method for interior permanent magnet synchronous motor (IPMSM), a sensorless control of IPMSM with triangular transform (TT) current self-demodulation in the estimating d-q axis is proposed. Firstly, the HF currents estimated on the d and q axes are multiplied, and the resulting signal is constructed through TT to achieve phase shift compensation of positive and negative sequence HF currents. At the same time, a position error signal is constructed. Then, a low-pass filter is used to extract the position error signal and achieve self-demodulation of the current. The experimental results show that this method reduces the average position error by 15.0% under steady-state conditions and reduces the fluctuation range of position error by 17.6% under full load conditions.
