With their cost-effective manufacturing process, hybrid stepper motors (HSMs) are a popular choice for position control in low-power industrial applications. These versatile motors offer a compelling solution for reducing system costs and size since at standstill/low speeds, HSMs typically have higher torque density with respect to low-power permanent magnet (PM) motors. This higher torque density determines a reduced use of rare-earth PMs and, therefore, a lower environmental footprint. In practical applications, the commonly used microstepping control faces low efficiency, low dynamic performance, vibrations, and a variable maximum continuous torque depending on the working point. In this paper, the operating region of an HSM is extended in the field-weakening (FW) region, showing how field-oriented control (FOC) with FW allows one to strongly increase the drive performance with a slight cost increase thanks to the availability of low-cost magnetic encoders. Due to the fact that FOC provides only the requested current, the HSM faces lower temperatures, lower insulation degradation, and lower permanent magnet demagnetization issues. An experimental evaluation comparing the commonly used microstepping and the proposed FOC with FW is performed on four commercial HSMs with different DC voltage power supplies using an industrial test bench. In particular, the experimental campaign has a focus on steady-state conditions in the case of the maximum continuous torque, showing the advantages of FOC with FW because the advantages in transient conditions are well known.

This paper proposes new torque control of an induction motor, which is robust against primary resistance and adaptable to leakage inductance, magnetizing inductance, and secondary time constant, The control is based on flux feedback with a Bur simulator, Since the simulator is based on a rotor current model, it is independent of the primary resistance, but uses the magnetizing inductance and secondary time constant values to estimate the flux, Parameter mismatch in the simulator detrimentally affects flux and torque responses, In order to compensate for degradation of the responses, an identifier for the magnetizing inductance and the secondary time constant is introduced, The identifier is insensitive to the primary resistance because it is based on instantaneous reactive power of the motor, Also, a leakage inductance identifier is introduced to achieve perfect compensation, which is robust against other parameters owing to instantaneous harmonic reactive power, To verify feasibility of the proposed technique, digital simulations and experimental tests have been conducted, The results have proven excellent characteristics of the drive system, which confirms validity of the scheme.

This is a further study of two previous articles of the authors. The simulation model includes saliency and almost all common imperfections of linear permanent magnet synchronous machine. Based on the same model, three types of control have been applied to drive the lift car for a typical fully loaded upward journey, namely field-oriented control, which was used in two previous articles, direct force control (conventional direct torque control on a linear machine) and a newly proposed direct speed control (a new direct torque control method that could be used in the lift industry). The performances in terms of speed accuracy during start-up and rated speed operation, power and energy consumption have been studied. The conclusion is that for such a new application in the lift industry, at this moment in time, the more conventional field-oriented control is highly recommended. Two new findings are reported. Direct speed control that involves a simpler circuitry and reasonable speed control is proposed, although there is always a small steady-state error due to the absence of a proportional-integral controller. Conventional direct torque (force) control involves continuous integration to estimate the magnetic fluxes, which is not applicable to a permanent magnet synchronous machine with saliency. A new definition to analytically estimate the magnetic flux linkages in real time is also proposed. It should be noted that field-oriented control is superior at this time. When technology continues to get advanced, direct force control and direct speed control may one day be more appropriate for linear permanent magnet synchronous machine application. The software to perform the simulation has been uploaded to the BSER&T/SAGE website.

This paper presents a novel approach to the field-oriented control (FOG) of induction motor drives. It discusses the introduction of artificial neural networks (ANN's) for decoupling control of induction motors using FOC principles. Two ANN's are presented for direct and indirect FOC applications. The first performs an estimation of the stator flux for direct field orientation, and the second is trained ten map the nonlinear behavior of a rotor-flux decoupling controller. A decoupling controller and flux estimator were implemented upon these ANN's using the MATLAB/SIMULINK neural-network toolbox. The data for training are obtained from a computer simulation of the system and experimental measurements. The methodology used to train the networks with the backpropagation learning process is presented. Simulation results reveal some very interesting features and show that the networks have good potential for use as an alternative to the conventional field-oriented decoupling control of induction motors.

The hysteresis band controller offers excellent dynamic performance. It has been widely researched and applied to the voltage source inverter and inverter fed drives, however it has not been investigated within the context of a matrix converter or a matrix converter based motor drive. In this study, both fixed-band and sinusoidal-band hysteresis current controllers are proposed and developed for a direct matrix converter. A comprehensive comparative evaluation of the two methods is then carried out. Both methods have fast dynamic performance and they inherently integrate the line modulation technique of the virtual rectifier stage into the overall modulation. Surge currents are prevented with the proposed scheme. The sinusoidal-band hysteresis controller demonstrates lower total harmonic distortion at the expense of higher average switching frequency, which is only significantly observable at very high sampling frequencies. The proposed controller is integrated with the field-oriented control to drive a matrix converter fed permanent magnet synchronous machine. The proposed methods are simple and incur a light computational burden, which advances the practical applications of matrix converters in AC motor drives. The simulation and experiment results demonstrate the effectiveness and feasibility of the proposed scheme.

Electromagnetic slip coupling (EMSC), like other contactless transmission devices, has lots of advantages over contact transmissions such as clutch function, continuous speed regulation, and no mechanical wear. Nevertheless, the EMSC has inherent slip energy especially under the large-slip condition, which leads to low efficiency. A novel energy-regenerative EMSC was developed including wound-type EMSC and the energy-regenerative apparatus for slip energy recovery. To improve recovery efficiency of the EMSC, the field-oriented control strategy was proposed. In this case, the mathematical model of EMSC under synchronously rotating coordinate system was constructed and verified by experiment. Since direct-axis component and quadrature-axis component of current in three-phase windings of the EMSC are coupled, the feed forward decoupling control approach was employed. Space vector pulse width modulation technique was utilized to eliminate harmonic components of current in three-phase windings. Simulations and experiments were carried out to validate the proposed control strategy. The results showed that the voltage and current in three-phase windings were almost in-phase, the current only contained few of harmonic components, and slip energy of the EMSC decreased by 82.5%. In conclusion, the field-oriented control strategy is conducive to recycle the slip energy of the EMSC efficiently.

This paper presents a method of designing a three-phase wireless power transfer (WPT) transmitter analogous to the stator windings of a three-phase, two-pole electrical machine. A method of deriving the required transmitter coil currents based on lateral receiver misalignment is presented, wherein the transmitter currents are decomposed into direct and quadrature axis components. This decomposition simplifies the derivation of the transmitter currents required to minimize copper losses for a wide range of receiver misalignment by reorienting the transmitter magnetic field toward the receiver. Based on the required transmitter current, the required series compensation capacitors and transmitter voltage sources needed for unity power factor operation are calculated. Simulation results are shown for a 3.3-kW system utilizing a receiver-side voltage-doubling rectifier and 300-V battery. Finally, experimental results on a 1-kW prototype are shown, where a coil efficiency of 95.17 at perfect receiver alignment and 90.52 at 20-cm lateral misalignment was measured.

This paper presents the field-oriented control (FOC) of a five-phase induction motor (FPIM) fed from a three-to-five phase direct matrix converter (DMC). The article focuses on the modulation and control of the three-to-five phase DMC, which discusses minimizing the problems associated with switching vector selection, sector identification, switching sequence selection, and dwell-time calculations. The DMC is controlled from the space vector pulse width modulation (SVPWM) technique, eliminating the x-y components of space vectors. Moreover, the matrix converter can perform unity power factor control at the input side. The FPIM is sourced from a DMC, and the FOC technique is applied to control the drive. The dynamic characteristics of the drive are succeeded for different loading conditions. The proposed work is simulated in Simulink/Matlab environment and further verified through practical experimentation. The control signals of the IGBTs are generated through FPGA embedded in dSPACE 1006. The experimental and the simulation results prove the practicability of the FOC to FPIM fed from a DMC.

This paper presents a systematic scheme to determine the optimal torque trajectory of a single-sided permanent magnet axial-flux motor (SPMAM) along with its operational constraints on both the winding currents and the speed induced voltages. Appropriate projection of the stator currents to achieve an optimal ratio of the machine propulsive/axial forces has been confirmed through detailed numerical and analytical studies. From these evaluations, a feasible operational guidance for SPMAM field-oriented control scheme realizations can be suitably provided.

In the task of electrification in various fields, the electrical machine is an important component. Current research show a rising interest in multiphase types, because of their advantages like inherent fault tolerance or lower current per phase. In this paper, the reduced order model of a nine-phase permanent magnet synchronous machine is developed and analyzed. The reduced order model is built using a lookup table created by simulation of certain operating points in an FEA model. To reduce calculation time, current and flux values are transformed into dq-coordinates. Two cases are considered: the healthy and an inter-turn short circuit fault case. For both cases the same control topology, a field-oriented control, with the same parameters is used. The healthy case is validated with an analytical model. The faulty case is then analyzed to firstly visualize the impact of the fault in the control scheme and secondly identify attributes, such as certain harmonic components, to detect this fault scenerio. With a reliable detection, a fault-tolerant control can be applied in future papers.
