Special Issue Information

Dear Colleagues,

With the future requirement of reducing CO2 emissions and therefore producing more and more electrical energy, AC generators will undergo ever-increasing development. To meet this challenge of producing continuously increasing quantities of electrical energy, the new generator types, whether they are low or high power, will have to ensure continuity of service by being ever more fault-tolerant.

A suitable solution to increase the reliability of a generator is to use a multiphase machine with symmetrical or asymmetrical structure. Indeed, with this configuration, an electrical fault on the machine or on the converter does not induce the shutdown of the electrical energy production, since three phases are remaining; this lies in contrast to classical solutions designed around three-phase machines.

Nevertheless, in this fault mode, due to the unbalances between the stator and rotor sides, the quality of the produced energy can be significantly impacted in terms of harmonics, as an example.

Therefore, advanced control strategies must be applied to multiphase machines to cope with this unwanted behavior during fault mode.

This Special Issue focuses on the development of fault-tolerant advanced control strategies for multiphase induction generators, whether they are low or high power.

Contributions may concern, for example, self-tuning, intelligent control, fuzzy control, sliding mode control, or predictive control techniques, among others. Particular attention will be paid to the experimental applications of the proposed control techniques.

Microhydraulic turbines offer a promising solution for decentralized energy production, suitable for both grid-connected and standalone applications, due to their compactness and high efficiency. This paper introduces a control approach for such systems employing microhydraulic turbines as distributed generators (DGs), utilizing six-phase induction generators for electricity production. This study emphasizes control strategies for both grid-connected and standalone modes utilizing proportional-integral (PI) controllers. An integrated energy storage system based on Li-Ion battery technology is also implemented to store the excess energy and compensate for production deficits to meet demand. The results obtained using MATLAB/Simulink demonstrate efficient and reliable power management among production sources, the grid and the local load, highlighting the unique contribution of employing a six-phase induction generator with the energy storage system.

This paper introduces robust nonlinear controller strategies for multiphase induction machines, aiming to enhance operational reliability under healthy and faulty conditions, including stator phase and converter leg openings. Due to the induction machine’s inherent nonlinearities and parameter variations, a robust control is required. The study evaluates the effectiveness of the sliding mode control with linear feedback and switched gains, the fuzzy proportional integral control, and their combined application in both healthy and faulty modes. The experimental assessment involves a symmetrical six-phase induction machine in generation mode, with comparisons with a classic proportional integral controller for inner current loop regulations. Experimental results show that the fuzzy proportional integral controller presents the best performance by minimizing torque ripples during both healthy and faulty operations. Full article

Currently, electric machines predominantly rely on costly rare-earth NdFeB magnets, which pose both economic and environmental challenges due to rising demand. This research explores recent advancements in machine topologies and magnetic materials to identify and assess promising solutions to this issue. The study investigates two alternative machine topologies to the conventional permanent magnet synchronous machine (PMSM): the permanent magnet-assisted synchronous reluctance machine (PMaSynRM), which reduces magnet usage, and the wound-field synchronous machine (WFSM), which eliminates magnets entirely. Additionally, the potential of ferrite and recycled NdFeB magnets as substitutes for primary NdFeB magnets is evaluated. Through detailed simulations, the study compares the performance and cost-effectiveness of these solutions against a reference permanent magnet synchronous machine (PMSM). Given their promising performance characteristics and potential to reduce or eliminate the use of rare-earth materials in next-generation electric machines, it is recommended that future research should focus on novel topologies like hybrid-excitation, axial-flux, and switched reluctance machines with an emphasis on manufacturability and also novel magnetic materials such as FeN and MnBi that are currently seeing synthesis challenges.
