“…However, this poses some problems, such as complication of estimation algorithms. A method has been proposed to use estimation with HF signal injection in high speed range as well [10], but there is a problem that superposed voltage saturates in high-load region.…”

SUMMARY This paper presents a new position sensorless control system for an interior permanent magnet synchronous motor (IPMSM). The proposed method is based on the extended electromotive force (EMF) and voltage injection synchronized with a pulse‐width modulation carrier. The proposed method does not need to switch the estimation method by speed in order to estimate the magnetic pole position by extended EMF, even at low speeds. Further, the amplitude of the superimposing voltage is changed according to the extended EMF; the applied voltage is not saturated in the high‐load and high‐speed regions. The effectiveness of the proposed sensorless control system was verified experimentally.

“…Therefore, the use of these methods cannot be applied to IPMSM drives at low speeds or at a standstill because little or no EMF is generated in the low-speed region. The other method used to estimate the pole position is by superimposing high-frequency components into the armature voltage commands of the motor [10]- [15] . This method is based on the magnetic saliency effect depending on the pole position, the current response by applying a pulse voltage, and the generated voltage high-frequency components current injection.…”

-Various methods have been proposed to identify the flux position in an interior permanent magnet synchronous motor (IPMSM) without the use of mechanical sensors. To achieve this, a method that uses both the back electromotive force (EMF) and the saliency to identify the flux position in the IPMSM without the injection of high-frequency components at low speeds has been reported [16] . This method was then extended in order to drive the motor with no load to a light load [17][18] . We propose a combination of these methods with different proportional-integral (PI) controllers for controlling di dest/ dt and di qest /dt. We also introduce compensation values F L and F H to reduce the position error when the estimation rule is being selected.

“…This method does not require data on the driving voltage and current, and hence stable phase estimation can be accomplished even at zero speed when the driving voltage S/N decreases considerably [1][2][3][4][5][6][7][8][9][10][11][12][13][14][20][21][22].…”

“…Initial research on high-frequency voltage injection dealt with high-frequency voltages at constant amplitude regardless of the rotor speed [3][4][5][6][7][8][9][10][11][12][13][14][20][21][22]. Such constantamplitude high-frequency voltage injection can be divided into methods using a square-wave high-frequency voltage [6,[20][21][22] and those using a sine-wave voltage [3][4][5][6][7][8][9][10][11][12][13][14].…”

SUMMARYThis paper proposes a new generalized high-frequency voltage injection method for sensorless drive of salient-pole permanent-magnet synchronous motors. The injected high-frequency voltage has a unique spatially-rotating elliptical shape, with the amplitudes of both the major and minor axes varying with the motor speed, and can be designed by selecting a design parameter. The high-frequency current caused by the injected voltage, which has information on the rotor phase to be estimated, is speed-independent, that is, is not affected by the motor speed at all. Consequently, the rotor phase can be estimated in a wide speed range from zero to the rated speed. By selection of the design parameter, the properties of the high-frequency current can be adjusted appropriately to the associated motor-drive system consisting of a motor and an inverter. As a versatile phase estimation method for estimating rotor phase using the high-frequency current, the "mirror-phase estimation method" is reconstructed and reproposed.
