“…Among the control approaches, the current shaping control method is usually adopted to reduce the SRM vibration and noise in the early stage of the research, such as the turn-on and turn-off angle advanced shift method [10], the random control angle method [11]; the two-stage [12] or three-stage commutation method. Due to their piezoelectric properties, lead zirconate (PZT) actuators have become an alternative method for semi-active/active vibration reduction [13,14]. However, all these control solutions in [13,14] require additional components-PZTs.…”

“…Due to their piezoelectric properties, lead zirconate (PZT) actuators have become an alternative method for semi-active/active vibration reduction [13,14]. However, all these control solutions in [13,14] require additional components-PZTs. Since the main source of the vibration is the variation of the radial force, it inspires the propositions of control strategies aiming to reduce the vibration by controlling the radial force directly [15][16][17][18][19].…”

Due to their inherent advantages such as low cost, robustness and wide speed range, switched reluctance machines (SRMs) have attracted great attention in electrical vehicles. However, the vibration and noise problems of SRMs limit their application in the automotive industry because of the negative impact on driver and passengers’ comfort. In this paper, a new control method is proposed to improve the vibratory and acoustic behavior of SRMs. Two additional control blocks —direct force control (DFC) and reference current adapter (RCA)—are introduced to the conventional control method (average torque control (ATC)) of SRM. DFC is adopted to control the radial force in the teeth of the stator, since the dynamic of the radial force has a large impact on the vibratory performance. RCA is proposed to handle the trade-off between the DFC and ATC. It produces an auto-tuning current reference to update the reference current automatically depending on the control requirement. The effectiveness of the proposed control strategy is verified by experimental results under both steady and transient condition. The results show that the proposed method improves the acoustic performance of the SRM and maintains the dynamic response of it, which proves the potential of the proposed control strategy.

“…To make this method more effective, a robust shaping technique [10] is employed in which a bandpass filter was introduced into the control strategy to extract the current harmonics within a range. Due to the piezoelectric property of the PZT, it has become an alternative method for vibration reduction [10] - [15], where the semiactive and active vibration controls based on PZT are proposed, and the numbers and the placement of piezoelectric actuators were optimized by genetic algorithm to reduce the vibration further. In addition, several methods have been proposed to control the radial force directly.…”

The inherent advantages such as high robustness, low cost and high starting torque have made switched reluctance machine a strong candidate for electric vehicle applications. However, the serious vibration and acoustic noise are very troublesome. In this paper, a semi-analytical vibration prediction model is developed and an enhanced vibration reduction method is presented via random-varying turn-off angle control that is based on the mechanical property of switched reluctance machine. In this method, a random-variation-frequency sine function is adopted to make the turn-off angle vary with time. At first, a magneto-mechanical coupling model is presented, then the principle of the control strategy is introduced. Next, simulation results are presented under different operating conditions, which validate the effectiveness of the proposed method.

“…As it is preponderant at usual rotation rates, magnetic noise has been deeply investigated (see [4,5] for some examples). In the case of SRM, many strategies have been developed to reduce it : acting on the excitation waveforms ( [6,7]), modifying the motor design [8] or adding some extra devices to realize active reduction of vibration [9]. On the contrary, studies on aeroacoustic noise dedicated to electrical motors are quite rare in the literature.…”
