Author ProfileAbstract
IPMSM drive systems which are driven by matrix converters have many
advantages, including one-stage power conversion, high efficiency,
bidirectional power transfer, near unity input power factor, and low
input current harmonics. However, the DC-link voltage of the
matrix-converter is varied from 0.866 to because a large electrolytic
capacitor is not used. These voltage variations deteriorate the dynamic
current and speed responses and reduce the adjustable speed range of the
IPMSM drive systems. In addition, the variations of the external load
and inertia are very large for matrix-converter based drive systems. To
solve this problem, two adaptive controllers are investigated in this
paper for matrix-converter PMSM drive systems. From the experimental
results, the proposed two adaptive speed controllers are superior to the
PI speed controller, including faster transient responses, better
tracking abilities, and greater robustness. As a result, the proposed
matrix-converter based IPMSM drive system is suitable in many industrial
applications.15 Apr 2024Submitted to The Journal of Engineering 28 Apr 2024Reviewer(s) Assigned
