Experimental Comparison of Robust Control Algorithms for Torque Ripple Reduction in Multiphase Induction Generators

“…We already know that if the RPs of each current axis (dq) reach the switching lines, we will have . 2) . Thus, the final expressions of the switching lines derivatives can be obtained:…”

“…In today's environment, where renewable energy and electric mobility are continuously expanding, rotating machines endorse a role of great importance. This situation boosts the need for the next generation of electrical machines to design and develop more high-performance rotating machines [1][2][3][4]. In this way, multiphase machines provide various benefits over conventional three-phase arrangements, including enhanced fault tolerance (e.g., loss of phases or converter legs) [5,6], less power per phase [7], and a substantial number of degrees of freedom [8,9].…”

A Novel, Simple, and Flexible Fault-Tolerant Control Algorithm for Multiphase Electrical Machine Operation Under Open Circuit Faults

“…Over the past decades, multiphase machines have gained significant relevance in both the scientific and industrial communities, due to their intrinsic features of fault-tolerant capability, which brings undoubted advantages to many applications in which safety is a very critical aspect, such as aerospace and automotive, providing also higher efficiency and flexibility concerning their three-phase counterparts [1][2]. However, it appears evident that the adoption of a higher number of phases leads to a higher complexity during the design phase of the machine, as well as for the control methods to be adopted for the related electric drive [3][4].…”

Design and Optimization of a Five-Phase Permanent Magnet Synchronous Machine Exploiting the Fundamental and Third Harmonic

“…In a five-phase machine, for example, it is possible to exploit the third harmonic to generate a torque, which provides an additional possibility to boost performance. In addition, it allows for the use of limited voltage and current power converters in high-power applications [2][3][4]. In the scientific literature, studies dealing with the design and control of multiphase machines mainly focus on high-power applications for different fields, such as marine current turbines [5], offshore wind turbines [6], and aerospace applications [7].…”
