“…At this point it is good to note that due to the high frequency nature of the injected pulse the leakage flux paths on the stator are excited, the observed effect is that of the stator leakage inductances being modulated by the main flux saturation. This variation is generally given in [1] by:…”

Abstract-This paper considers the general principles of saliency tracking in AC machines. Special attention is given to pulse type injection for the extraction of a rotor or flux position signal. The saliency is tracked by measuring the current derivative resulting from voltage 'test' vector application. Results show tracking of 'saturation' saliency on a standard induction motor to be used for sensorless control of ac machines in the low and zero speed region.

“…To protect the PM and keep it constant, the field-oriented control will keep the direct current component (i d ) equal to 0; therefore, the stator flux is only created from the quadrature current component (i q ) and is proportional to the l q value, as written in Eq. (20). In practical implementations, the currents are provided from actual measured values, but the voltages are not measured because they are PWMs.…”

“…The first one depends on the superposition of the fundamental voltage vector of a high-frequency injection either in the alpha/beta frame [15,16] or in a rotating d/q synchronous frame [17,18], and the second one is based on a modification of the fundamental PWM pattern to include a voltage pulse test [19,20].…”

The most common control technique for such PMSM MC-fed drives is the so-called Field-Oriented Control (FOC), which requires the permanent magnet flux position to achieve high dynamic performance. Encoders or resolvers are the most common sensing devices used for such a purpose, which not only increases the total cost of the PMSM drive but also adds extra electronics and cabling that may cause failures. This paper investigates and proposes an all range (from zero to full) speed hybrid sensorless FOC. The novelty of this paper relies on the use of a hybrid sensorless four quadrant FOC that averages the needed angle estimation from a model based angle estimator and a voltage pulse test injection angle estimator when feeding the PMSM with an MC instead of a standard voltage source inverter. Speed reversal and load impact simulation results are included, fully supporting the claims made in this paper.

“…These researches focus on the model based sensorless control, direct torque control and high frequency injections [15,16,17,18,19]. This paper introduces a new method to track the saturation saliency in five-phase PMSM drives to obtain the rotor position through measuring the dynamic currents responses of the motor due to the IGBTs switching actions [20,21,22]. It uses the fundamental PWM waveform obtained using the multi-phase space vector pulse width modulation only.…”

The rotor position is obtained through tracking the saturation saliency by measuring the dynamic currents responses of the motor due to the IGBTs switching actions. It uses the fundamental PWM waveform obtained using the multi-phase space vector pulse width modulation only. The saliency tracking algorithm used in this paper doesn't only improve the quality of the estimated position signals but also guarantees a minimum current distortion through reducing the modifications introduced on the PWM waveform. Simulation results are provided to verify the effectiveness of the proposed strategy for saliency tracking and current distortion minimizing of a five-phase PMSM motor drive over a wide speed ranges under different load conditions.
