“…The modeling was performed by taking into account the classical PMSM electrical equations and an asymmetric inductance matrix, showing a dependency between self and mutual inductances in the neutral-point voltage. Finally, in order to enhance the accuracy and the robustness of the sensorless control of PMSM drives, two novel techniques based on the utilization of the neutral-point voltage are proposed in [27,28]. The first work deals with a pulsating carrier signal injection while the latter utilizes a square-wave signal injection.…”

In the field of sensorless control of permanent magnet synchronous motors (PMSMs), different techniques based on machine anisotropies have been studied and implemented successfully. Nevertheless, most proposed approaches extract the rotor position information from the measured machine currents, that, when applied to low-power machines, might require high-bandwidth current sensors. An interesting alternative is given by sensorless techniques that exploit the star-point voltage of PMSMs, such as the direct flux control technique. This work aims at analyzing the conditions of applicability of such technique by considering a more thorough description of the machine inductance matrix. After a comprehensive mathematical description of the technique and characterization of the machine anisotropy information that is extracted from the star-point voltage, simulation as well as experimental results conducted on a test machine are presented and discussed in order to validate the proposed theory.

Specifically for the machine saliency-based methods, they can be divided into the discrete voltage pulses [1], PWM [2,3] and continuous carrier signals injections [4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], respectively.…”

This study presents the parasitic effects on different carrier signal injection methods with alternative sensing signals for the sensorless control of permanent magnet synchronous machines (PMSMs). The different carrier injection methods are the rotating injection in the stationary reference frame with carrier current sensing and with zero-sequence carrier voltage sensing, the pulsating injection in the estimated synchronous reference frame with carrier current sensing, and pulsating injection in the anti-rotating reference frame with zero-sequence carrier voltage sensing, respectively. The parasitic effects, e.g. the magnetic saturation, inverter non-linearity, iron and PM losses, torque ripple etc. will be fully analysed and compared for these different injection methods. All the theoretical analyses are validated by either finite-element analyses or experiments on a laboratory PM machine.

The position sensorless vector control of permanent magnetic synchronous motor is the method that implements the vector control by estimating the rotor position from the motor model in the basis of the voltage and the current signal of the motor without measuring the motor position directly. The sensorless vector control is divided into two methods: estimating the rotor position based on the stationary reference frame and rotational reference frame. This article presents the research results of more improved estimation performance by combining these two methods. First, we estimate the rotor position by using the open-loop estimation algorithm based on the stationary reference frame, evaluate the estimation error based on the model from the rotational reference frame and compensate the estimate in a feedback way with differences from the current measurements. At the same time, we also take the parameter errors included in the model into account. This article performed the experiment for the parameter identification and for the sensorless vector control, and demonstrated its effectiveness.
