Special Issue Information

Dear Colleagues,

The latest agreements from the 28th Conference of the Parties focus on reducing fossil fuel consumption and greenhouse gas releases. With these goals in mind, electric drives can be considered as an extended solution to reduce energy consumption, with a notable decrease in emissions. This trend promotes the adoption of electric drives in green energy generation and electric mobility. However, this expanded role necessitates the development of more competitive electric drives to meet the increasingly stringent requirements of industrial applications. In this regard, the use of multiphase technology or axial flux motors has been explored in a successful manner when higher requirements are expected, providing a considerable progress in motor drive performance. On the one hand, multiphase electric drives offer certain advantages over conventional three-phase systems. For instance, the implementation of multiphase technology permits a higher fault tolerance, a better current distribution for the same level of power/voltage, as well as the existence of a higher number of operating modes. On the other hand, axial flux machines exhibit a significant increase in the weight/power ratio, delivering satisfactory performance in applications where weight is a crucial factor, such as in electric mobility. In addition, the beneficial features of these technologies can be further enhanced when combined with the use of semiconductors based on SiC or GaN switches.

Considering the previous information, this Special Issue aims to provide an insight into the state of the art of more competitive electric drives based on multiphase systems, axial flux motors, or the new generation of semiconductors. By exploring these cutting-edge innovations, this issue aims to shed light on the recent progress in electrical machines and motor drives.

Prospective authors are encouraged to submit original research and survey papers for consideration in this Special Issue. The topics of interest may include, among others, the following:

- The control of multiphase electric drives.
- The design of multiphase machines.
- Fault tolerance in multiphase machines.
- Model predictive control for multiphase electric systems.
- Model free predictive control for multiphase electric systems.
- The integration of axial flux machines in electrical vehicles.
- The control of axial flux machines.

- Modeling axial flux machines.
- The impact of SiC/GaN switches on electric drives.
- Voltage source converters based on SiC/GaN switches.
- The design of modulation stages for SiC/GaN switches.

Variable speed drives are often controlled by a double-loop scheme in which a proportional integral controller takes on the speed loop. The tuning of this loop is a complex job. In most cases just mechanical variables are considered for tuning. This paper presents a new Pareto analysis incorporating mechanical and electrical variables. A state of the art finite state model predictive controller is used for stator current control. The analysis is performed using experimental data from a five-phase induction motor and considers considering commonly found performance indicators derived from experimental data. The results show undocumented connections between those performance indicators. The analysis not only helps in PI tuning but, more importantly, prompts for a revision of the methods usually utilized to report performance enhancements of new methods. Full article

The control of electric drives is an important topic due to the wide-spread use of such devices. Among these, multi-phase induction machines are gaining momentum in variable-speed applications. The usual control practice is the use of a speed Proportional–Integral loop that sets the current reference for an inner controller. This inner controller decides the voltage to be applied, which is realized by an electronic power converter. This paper presents an Artificial Intelligence (AI) scheme for tuning. It aims to optimize the usual figures of merit for drives. Moreover, tuning for both loops is tackled concurrently. The adjustment is performed relying on the operating region to address non-linear behavior. The results obtained using a five-phase induction motor illustrate that the proposed method can work in the entire operating range of the drive with improved results. Full article
