Optimized Pulse Patterns for Synchronous Machines with Non-Sinusoidal Back-EMF
<p>Permanent magnet synchronous machines (PMSMs) used in automotive applications typically have a small number of stator slots. This distorts the air-gap flux distribution, thus resulting in a non-sinusoidal back-electromotive force (back-EMF ...

ABSTRACT This work addresses the challenge of bidirectional trajectory tracking in solar‐powered wheeled mobile robots (WMRs), considering the mechanical structure, actuator‐driver, and power stage subsystems. Notably, this is the first study to explicitly model and control the actuator‐driver subsystem within this context. The proposed solution relies
