Abstract
The aim of this brief is to positively answer the following question. Is it possible to go beyond the limitations outlined in the very recent paper by Ortega et al. and show that the smooth version of the (maximum-torque-per-ampere) industry standard control scheme for non-salient-pole PMSMs (Permanent Magnet Synchronous Motors) - even including the outer Proportional-Integral control action on the rotor speed regulation error - guarantees global asymptotic (exponential on compact sets) stabilization of the desired equilibrium? The key technical point relies on the repeated use of the Persistency of Excitation Lemma, whereas a remarkable feature of the proposed analysis is constituted by the direct possibility of recovering, as a special case, the recent passivity-based arguments presented by Ortega et al. for non-salient-pole PMSMs. (C) 2020 Elsevier Ltd.
