This research work designs an improved iterative learning control (ILC) with DC-link balancing capability for three-level neutral-point-clamped (3L-
NPC) inverter-fed permanent magnet synchronous motors (PMSMs). Unlike the classical ILC, which depends only on information captured from the
last iteration, the proposed ILC approach is capable of storing the data of the state errors from a number of preceding iterations. Henceforth, the
designed control method incorporate the simple DClink balancing algorithm. It encompasses the integration of essential dynamics, with a dual focus
on achieving not only rapid dynamic response but also maintaining a satisfactory steady-state performance. The efficacy of the proposed control
approach is validated by simulation as well as experimental findings implemented with a PSIM software package and an experimental PMSM test rig
with a TMS320F28335-DSP, respectively. Therefore, the improved transient response and steady-state performance indicate that the suggested control
approach outperforms the standard approach.
