Improved dynamic control for permanent magnet AC (PMAC) machine in the field weakening region

摘要

This paper presents a study of a predictive torque and flux control in the constant torque region and in the field-weakening one of Permanent Magnet Alternate Machines (PMAC) fed by a Voltage Source Inverter (VSI). It is based on the step-by-step determination of the inverter feeding voltage as a function of the current references, by taking into account both the steady state and the transient electrical constraints. Experimental results confirm the validity of the proposed approach and the possibility of achieving very good dynamic performances.
