This article proposes a discontinuous current vector control method for a three-phase switched reluctance motor driven by an asymmetric H-bridge converter. The proposed method enables vector control with three-phase discontinuous currents, improving the torque per ampere ratio and the efficiency of both the converter and motor compared to conventional continuous current vector control. Moreover, the proposed method reduced vibration and acoustic noise, as the control parameters can be designed using a mathematical model, and the switching frequency can be determined by a carrier signal, similar to conventional vector control. This article derives a torque equation considering discontinuous current conditions and describes the configuration of the control system. In addition, the effectiveness of the proposed method is demonstrated through simulation and experimental verification. In the experimental verification, the efficiency of the proposed method was improved by a maximum of 7.73 percentage points in the converter efficiency, 4.06% points in the motor efficiency, and 9.12% points in the system efficiency compared to the conventional vector control method. Furthermore, FFT analysis of acoustic noise showed a noise level reduction of up to 36.0 dB at 10.9 kHz compared to current hysteresis control, making it equivalent to the noise level of conventional vector control.

This article presents a novel fault-tolerant control (FTC) strategy for three-phase induction motor drives designed to maintain adequate operation during a fault occurring on either the electrical machine or the power converter sides. The proposed FTC ensures uninterrupted operation through software and hardware reconfigurations, which are specifically related to the fault type, leveraging a flexible machine and power devices fault-tolerant inverter topology. The system employs modified voltage references and asymmetric transformation matrices to adapt to inverter or motor faults while maintaining balanced operation and reduced torque, flux, and speed oscillations. Simulation and experimental results demonstrate the effectiveness of the proposed strategy in restoring operational integrity with limited performance degradation, highlighting its flexibility and suitability for critical industrial applications.

The recent advances in computational power and motor design software, supported by finite elements analysis (FEA), permit accurate prediction of the losses and electromagnetic performance of the machine at the design stage. Anyway, the simulation accuracy strictly depends on the real motor geometry and material properties, which are affected by the manufacturing process. This article offers a systematic method for accurately calibrating the electromagnetic FEA models, permitting to consider the production process within the motor design stage. A synchronous reluctance motor prototype is designed, manufactured, and experimentally characterized, and the measured flux and torque characteristics are exploited for ex-post calibrating the FEA model of the machine. This approach led to a reduction in torque estimation error from 18% to 4%, and an improvement of the flux maps evaluation, thus enhancing and validating the design procedure and permitting further optimization steps of machines with similar geometry and dimensions. The effects are particularly evident in the proposed motor due to the reduced size of the rotor flux barriers, stator teeth, and yoke. The mechanical tolerances are analyzed through a Monte Carlo analysis covering different areas of the machine. Then, the effects of uncertain airgap length and iron degradation due to the manufacturing process are considered, determining an equivalent degraded BH curve.

The virtual synchronous generator (VSG) concept is a well-established control solution that facilitates the integration of power electronics-interfaced renewable sources into the electric grid. The VSG algorithm enables power converters to support the grid in case of voltage dips by injecting a large short-circuit current. However, a current limitation strategy must be implemented to address the hardware limitation of power converters. As demonstrated in the literature, the current constraint affects the VSG’s dynamics by limiting the output power, thus causing a substantial acceleration of the virtual rotor and potentially leading to a loss of synchronism. Several available solutions utilize the measured actual active power as feedback, thereby modifying the VSG with complex control algorithms. On the other hand, this article proposes a different approach, highlighting the benefits of using the virtual power instead of the measured power feedback for the most adopted limitation strategies available in the literature. This paradigm shift leads to a significant improvement in stability without requiring fault detection capability or switching the control structure, as demonstrated both theoretically and experimentally in this article.

Robotic systems, such as legged robots or industrial robots used in manufacturing and humanoid assistance, rely on robotic joints to perform multi-degree-of-freedom motions. Each joint typically incorporates a motor and a gear to drive its motion. Power delivery and control for these joints are usually achieved through cables for power and data transfer, which are routed through the joints. However, as the joints move, these cables bend and flex, leading to eventual failure due to the limited number of bending cycles they can withstand. In addition, in high-precision joints, cable slack can disrupt position control accuracy. To address these challenges, this article investigates wireless power and data transfer for robotic joints. The proposed approach leverages a closed magnetic core for power transfer, minimizing stray magnetic fields, and uses photodiode-based communication with a custom-developed control circuit. The approach is validated through experimental measurements and benchmarked against existing solutions in the literature. We demonstrate a system capable of transferring 200 W of power and achieving a data transfer rate of 2 Mbit/s, with the total weight of all components being 96 g.

In the growing context of integrating renewable sources and storage systems in the electric grid, the virtual synchronous machine (VSM) concept represents a valid solution to embed grid support functionalities in grid-tied converters. The knowledge of grid impedance is required to exploit properly the VSM features in providing grid ancillary services, such as inertial behavior, harmonics compensation, as well as short-circuit current injection during faults. Therefore, this article proposes a closed-loop grid impedance estimator, specifically designed for VSM applications, which is directly integrated into the VSM model. The grid resistance and inductance estimations are performed in real time, without the need of data elaboration through complex mathematical tools, which are usually required by methods available in the literature. The proposed solution leverages the VSM dependency on grid parameters when an amount of current is directly injected into the grid without being processed by the VSM itself. The proposed estimator inherently rejects the noise on voltage and current measurements, thus providing reliable results for real world operating conditions affected by disturbances. It can be easily tuned according to the desired filtering capability and estimation process duration. Experimental tests on a 15 kVA grid-tied inverter validate the proposed solution.

This article presents MatWPT, an innovative software developed to support designers during the analysis and development of wireless power transfer (WPT) systems. The software, developed as a MATLAB toolbox, receives the key system characteristics as inputs, such as compensation topology, operating frequency and desired output power. Then, using evolutionary optimization, provides potential design options for meeting the performance criteria defined by the designer, in terms of output power and efficiency. Unlike the solutions available in the literature, the proposed technique allows the component tolerances to be considered. In fact, the tool implements an automatic Monte Carlo analysis to estimate the probability that a specific solution will achieve the expected performance levels, given the fabrication tolerance of the components. This represents valuable information for mass production, as WPT systems are typically very sensitive to component variations. Besides presenting the toolbox and its functionalities, this article also reports the extensive experimentation that the authors conducted on WPT systems, designed using MatWPT. The results obtained with the toolbox are in excellent agreement with the measurements.

The short-time thermal transient (STTT) test is an efficient and precise method for determining the winding thermal capacitance and winding-to-back-iron thermal resistance in ac motors. Traditionally validated for industrial motors, the STTT procedure involves a brief dc excitation with motor phases connected in series, followed by analysis using a first-order lumped parameter thermal network. However, for traction motor drives where phase terminals may be inaccessible, the standard all-in-series STTT procedure is not feasible. Moreover, in such highly loaded traction motors, the estimated thermal parameters are sensitive to dc excitation duration, making the first-order STTT model unsuitable. This article presents an STTT model of higher order along with an optimized testing sequence and data processing approach, extending the applicability of this method to traction and high-power-density motors. Experimental validation on two commercial supercar traction motors demonstrates the effectiveness of the proposed model and procedure, to be considered an upgrade of wider and more general validity of the existing first-order STTT method.

The article deals with the control structure and implementation of a fully integrated two-phase cooling (TPC) system for power converters. A suitable testbed has been properly designed and built to perform the experimental campaign for the performance evaluation of the neural network-based control structure applied to an advanced multivariable TPC system. With respect to traditional cooling approaches, the proposed arrangement allows a greater extraction of the heat at a very low flow rate of the cooling fluid, even with standard industrial-grade heat-sinks. The technology could be implemented for the next generation of power electronics converters. The controllability of such a cooling system is still an open issue in many cases, and the proposed approach tries to suggest a feasible approach, which could be implemented on an industrial grade control board.

This article presents a novel method for torque ripple reduction in switched reluctance motors (SRMs). The proposed method relies on current waveform shaping. The shaped current profile is an adjusted version of a current waveform in the literature that reduces the acoustic noise of SRMs. The resulting proposed current flattens the torque waveform in addition to a significant reduction in acoustic noise. The proposed method is compared with several conventional square currents, as well as with the currents that are dedicated to acoustic noise reduction from the literature. The primary contributions of this article are the simultaneous minimization of torque ripple and acoustic noise through current waveform shaping, as well as the application of the current-waveform refinement method specifically for torque ripple reduction. Experiments and finite element analysis were implemented to achieve the comparisons in terms of current, torque, radial force, stator vibration, and sound pressure level.
