“…These points have been treated by different researches such as (Haque et al, 2003;Taniguchi et al, 2007;Kock et al, 2009;Foo and Rahman, 2010). But, the originality of this study focuses on optimal HFSI parameters choice concerning washing machine applications according to their specific characteristics.…”

“…• Transient signal injection based schemes which exploit the PWM signal in order to extract the rotor position or to inject discrete test voltage pulses in a defined direction (Raute et al, 2007;Belie et al, 2010;Vogelsberger et al, 2010) • Continuous high frequency signal injection based schemes which consist on injection of signal reported to a rotating high frequency voltage vector in the stator reference frame (α,β), (Perassi et al, 2005;Hu et al, 2008) or injection of signal reported to a pulsating high frequency voltage vector in a reference frame (d,q) synchronous with the motor saliency (Aihara et al, 1999;Sakamoto et al, 2001;Holtz, 2008;Wiedmann et al, 2009;Kock et al, 2009) Transient signal injection schemes are very complex to be implemented for practical real time systems whereas continuous high frequency signal injection schemes are based on a simple excitation and are easier to be experimentally implemented. However, continuous HFSI technique performance and robustness depend on the parameters choice of the high frequency signal injected in order to extract the rotor position or the rotor position error (Taniguchi et al, 2007).…”

Problem statement:This study investigates a novel optimized scheme of a High Frequency Signal Injection (HFSI) based sensor less technique in order to carry out a precise and robust rotor position error estimation of a Permanent Magnet Synchronous Motor (PMSM) drive designed for washing machines. The study was carried out for standstill condition, where precise position information was required for this application. Approach: In order to get rotor position error information, a PMSM high frequency model was considered in the estimated rotor reference frame (d,q). The impact of the HFSI technique parameters choice on the PMSM rotor position estimation performance was studied and experimentally tested, under various injection conditions. Results: The experimental results show that the amplitude of the high frequency current, resulting from injection, was not significant to carry out high performance rotor position estimation. In order to improve rotor position estimation performance and robustness, a modified demodulation of the high frequency current resulting from injection was proposed by using a high pass filter amplifier applied to PMSM measured currents. The novel proposed rotor position error extraction scheme was implemented on a dsPIC30F6010A and was experimentally validated on a 1kW washing salient pole PMSM. Conclusion: This study presents an improved high frequency voltage injection based sensor less control for Permanent Magnet Synchronous Motor (PMSM) designed for washing machines. The optimal parameters choice of the HFSI technique and the use of a high pass filter amplifier have allowed to take the most of the high frequency injected signal for extracting the rotor position error at standstill, compared to a conventional scheme.

“…However, at the low speed region, these methods fail to operate because the back EMF information is too small. Rather than the back EMF, the signal injection methods are based on the anisotropic properties of IPMSMs, caused either by the inherent saliency due to the machine geometry [12,13] or by the saturation of the stator iron [14]. Therefore, these methods can be utilized to estimate speed and position information in the low speed region, including zero speed.…”

Sensorless Control of Interior Permanent Magnet Synchronous Motor in Low-Speed Region Using Novel Adaptive Filter

This paper presents a novel position and speed estimation method for low-speed sensorless control of interior permanent-magnet synchronous machines (IPMSMs). The parameter design of the position and speed estimator is based on the sampled current rather than the motor electrical parameters. The proposed method not only simplifies the parameter design, it enables the estimator to work normally even in the condition that the electrical parameters are uncertain or varied. The adaptive filters are adopted to extract the desired high frequency current. The structure and corresponding transfer function are analyzed. To address the shortage of insufficient stop-band attenuation, the structure of the adaptive filter is modified to provide suitable bandwidth and stop-band attenuation simultaneously. The effectiveness of the proposed sensorless control strategy has been verified by simulations and experiments.

“…Whatever the kind of signal injection used, magnetic (cross)-saturation must moreover be taken into account to get a good position estimation under high-load condition, see Scapino (2000), De Belie et al (2005);Holtz (2008), Reigosa, García, Raca, Briz, and Lorenz (2008), Bianchi, Bolognani, and Faggion (2009), De Kock, Kamper, and Kennel (2009), Li, Zhu, Howe, Bingham, and Stone (2009), Sergeant, De Belie, and Melkebeek (2009), Raca, García, Reigosa, Briz, and Lorenz (2010, Bianchi et al (2011), Gong (2011), Sergeant, De Belie, andMelkebeek (2012), Szalai et al (2014), Wang et al (2014), Bolognani et al (2011) and Zhu (2014a, 2014b). Some model of the saturated PMSM is thus required for a good functioning of a sensorless control law; to be useful it must be rich enough to capture in particular cross-saturation but also simple enough to be used in real-time and to be easily tuned in the field.…”

Sensorless control of permanent-magnet synchronous motors at low velocity remains a challenging task. A now well-established method consists of injecting a high-frequency signal and using the rotor saliency, both geometric and magnetic-saturation induced. This paper proposes a clear and original analysis based on second-order averaging of how to recover the position information from signal injection; this analysis blends well with a general model of magnetic saturation. It also proposes a simple parametric model of the saturated motor, based on an energy function which simply encompasses saturation and cross-saturation effects. Experimental results on a surface-mounted motor and an interior magnet motor illustrate the relevance of the approach.
