“…In recent years, the synchronous reluctance motor (SynRM) has drawn attention due to several advantages – its low cost, durability, and high density [1–3]. The absence of rotor loss and slip frequency is a major advantage that the SynRM has over the induction motor [4]. Moreover, the SynRM is attractive due to its superior characteristics, including the fact that it does not require a permanent magnet.…”

This study proposes implementation of a predictive controller for a sensorless synchronous reluctance drive system. First, high-frequency voltage is injected in the α-axis. Then by measuring the α-β axis high-frequency currents, the rotor position of the SynRM can be estimated. After that, a predictive speed controller is implemented to improve transient responses, load disturbance responses, and tracking responses. To demonstrate its viability, a proposed 560 W sensorless drive system is implemented by using a TMS-320F-28335 DSP made by Texas Instruments and some circuits. Experimental results clearly indicate that the proposed high-frequency α-axis voltage injection method with a predictive speed-loop controller offers superior responses including faster transient responses, better load disturbance responses, and better tracking responses than a high-frequency d-q axis voltage injection method with a PI speed-loop controller.

Model-Free Current Loop Autotuning for Synchronous Reluctance Motor Drives

Synchronous reluctance motors are arousing lively interest as a possible alternative to the less efficient induction motors. An open issue is the effective tuning of the inner current loops because of the nonlinearity that cannot be overlooked. The present paper uses a relay feedback approach to perform autotuning without resorting to any parameter knowledge. The tuning is iterated at different working points, to get a uniform current control bandwidth everywhere. Unlike many solutions in the field, the algorithm is truly autonomous, in the sense that it also suggests a correct value for the bandwidth specification. The paper includes both simulation and experimental results, obtained on a laboratory prototype.

“…Despite the above techniques, only a few researchers have focused on advanced controller design for SynRM drive systems. For example, Zarchi et al [18] proposed an adaptive input-output feedback-linearisation-based torque control of SynRMs without using any position or speed sensors, whereas Wei et al [19,20] implemented an online tuning adaptive controller and a passivity-based controller for SynRM drives.…”

This paper proposes an adaptive controller with an improved high-frequency injection method for sensorless synchronous reluctance drive systems. A mathematical model is presented to show that the use of a high-frequency injection method that takes into account the effects of unequal mutual-inductances and the influence of speed reduces the rotor position estimation error. The adaptive speed control algorithm offers improved transient performance in comparison to typical proportional-integral (PI) controllers that are employed in sensorless drive systems. To demonstrate the viability, the proposed adaptive controller and the modified high-frequency injection method are implemented using a TMS-320F-28335A digital signal processor to control a 500 W prototype synchronous reluctance motor drive. Experimental results are presented to show that the transient, load disturbance, and tracking responses of the proposed drive system are superior in comparison to a drive that uses a PI controller. Both experimental and theoretical analyses clearly indicate that the proposed high-frequency injection method with an adaptive speed-loop controller offers improved performance in adjustable speed synchronous reluctance drive systems.
