DOI: 10.1109/tpel.2016.2607228
Abstract: Synchronous-frame proportional-integral (PI) curr-ent control is the most popular solution in industrial permanent-magnet synchronous motor (PMSM) drive systems. However, due to the nonlinearities from large parameter uncertainties and complex operating conditions, it is challenging to… read more here.
