Abstract Transportation electrification is gaining notoriety in recent years as to fulfill the aim of reducing the fossil fuels consumption and to increase energy efficiency. Accordingly, integrated starter alternator is a compelling method to convert conventional vehicles into hybrid ones. A deal of benefits can be reached by using ISA systems. In general, it provides vehicles performance enhancement and also reduces fuel consumption. This paper aims to present simulation results and preliminary experimental achievements with a power electronics-based prototype driving a permanent magnet synchronous machine (PMSM). The ISA operation is demonstrated throughout providing cranking torque and assistant torque for constant power and constant torque conditions and afterward the generation mode. Details of the hardware design and control strategies, which include an ADALINE neural network for properly find the mechanical position and the application of a metaheuristic technique to tune the controllers of the motor control, have been also addressed.

1 Introduction Nowadays, there is a great deal of work focused on the reduction in fuel consumption due to increasing awareness about environmental issues. Some environmental laws are being updated in order to preserve well-being around the world, and a plenty of areas are evaluated. Among them, the automotive industry comes under the spotlight due to the large number of vehicles on the streets and the companies’ efforts to constantly renew their fleets (Asaei, Farhangi and Fayazi 2007). Many research areas are focused on obtaining costeffective and environmentally friendly solutions for automobile industries. Electrification is the most promising solution (Bilgin et al. 2015). Indeed, transportation electrification is gaining ground in the modern scenario. Hybrid electric vehicles (HEV) are inserted as an excellent solution since it represents a smoothly transition from conventional to electric vehicles. Furthermore, due to the lack of charging station and relatively low autonomy, electric vehicles are kind of limited to urban trails; thus, HEV represents a viable solution by

combining the advantages of both types of vehicles (Jurca and Ruba 2017). With minor modifications, a conventional vehicle can be easily adapted to a hybrid one by using an effective integrated starter alternator (ISA), especially in Mild Hybrids (Faggion et al. 2008). Essentially, an ISA is a device in which only one machine can perform the functions of starting the internal combustion engine (ICE) and generating power. Initially, ISA system was developed in ord
