The integration of electromechanical actuators in the aircraft systems is one of the major key-point of the aerospace industry, thanks to their advantages, such us minor weight and major efficiency: this trend is called "More-Electric Aircraft".In this paper, a PM brushless motor has been designed and analyzed to integrate in an electromechanical actuator in a regional aircraft to control aileron/spoiler surface.As first step, an accurate selection of the active material has been made in order to have the best compromise between envelope and performance. Then, an optimization of the electromagnetic design has been performed in order to maximize the torque-to-current ratio at continuous operation.A surface permanent magnets machine with concentrated windings has been chosen and the proposed motor has the magnets directly glued on the surface of the steel nut. Moreover, in order to improve the power density, the high-performance CoFe electrical steel has been selected.Accurate Finite Element analysis and thermal verification have been carried out to ensure that the sized motor could cover the overall range of required performance avoiding overtemperature during the operation.

“…The adoption of this machine is due to the fact that it is characterized by a very simple structure, robustness, provides a large starting torque and a large speed range, is rare-earth-material free, and presents a high efficiency. In this way, it has been adopted for many applications, such as in electric and hybrid vehicles [4][5][6], aircraft and aerospace systems [7][8][9][10], home appliances [11], industrial tools [12], wind generators [11][12][13][14][15][16], pumping systems [17][18][19], mining [20] and storage systems [21,22]. However, a very important aspect is that this machine requires a power electronic converter.…”

The switched reluctance machine (SRM) is one of the most interesting machines, being adopted for many applications. However, this machine requires a power electronic converter that usually is the most fragile element of the system. Thus, in order to ensure high reliability for this system, it is fundamental to design a power electronic converter with fault-tolerant capability. In this context, a new solution is proposed to give this capability to the system. This converter was designed with the purpose to ensure fault-tolerant capability to two types of switch faults, namely open- and short-circuit. Moreover, apart from this feature, the proposed topology is characterized by a multilevel operation that allows improvement of the performance of the SRM, taking into consideration a wide speed range. Although the proposed solution is presented for an 8/6 SRM, it can be used for other configurations. The operation of the proposed topology will be described for the two modes, fault-tolerant and normal operation. Another aspect that is addressed in this paper is the proposal of fault detection and diagnosis method for this fault-tolerant inverter. It was specifically developed for a multilevel SRM drive. The theoretical assumptions will be verified through two different types of tests, firstly by simulation and secondly by experiments with a laboratory prototype.

“…SRM is also applied in aircraft electric brake system [5, 6] and roll control of a flight projectile [7]. Due to the high mean time between failure (MTBF), SRM mates the aerospace reliability requirements [8] properly, and is used for the medium‐sized aircraft [9].…”

In order to reduce the torque ripple for switched reluctance motor (SRM), the learning error preprocessing‐based torque–flux linkage recurrent neural network adaptive inversion control (TFRNNAIC) for SRM torque is proposed by the filter preprocessing and the non‐linear mechanism characteristics for SRM. In TFRNNAIC with the advantages of parallel and series–parallel structure, the torque feedback error learning method is employed to update the weights of the torque–flux linkage recurrent neural network. To suppress the ripple effectively in torque error used for the weight learning of the torque–flux linkage recurrent neural network and obtain an accurate TFRNNAIC, namely the torque–flux linkage model for SRM, the low‐pass filter preprocessing for the torque error is used. Moreover, the other low‐pass filter is executed to reduce the ripple in the output for the PD torque control. The superposition of outputs for TFRNNAIC and PD torque control is taken as the reference flux linkage. Compared with other control strategies, such as the classical parallel neural network control, the classical series–parallel neural network control and TFRNNAIC, the simulation results show that the learning error preprocessing‐based TFRNNAIC for SRM torque is capable of effectively reducing the torque ripple for SRM with the good recurrent performance.
