Flux-Weakening Strategies for a Five-Phase PM Synchronous Machine [PDF]
In order to get a low cost mild hybrid system, a global objective is to keep the actual thermal engine architecture. As consequence, the current clawpole synchronous automotive generator must be replaced by a new more powerful electrical machine but with

Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

A reservoir‐guided silver‐nanoparticle soldering strategy is developed for bending‐resistant 3D graphene–metal heterojunctions. Controlled hot‐plate evaporation confines conductive ink within the metal reservoir, suppressing spreading and protecting the LIG interface from deformation‐induced fracture.
