Abstract
This article exhibits a robust speed controller equipped with a self-tuner for permanent magnet synchronous motors (PMSMs), taking nonlinearity and model-plant mismatches into accounts. The first contribution of the proposed technique is to design a self-tuner for updating the cut-off frequency of target speed dynamics. The second one is to render the closed-loop system to recover the target tracking performance and remove the offset errors in the absence of integrators. A 5-kW prototype interior PMSM (IPMSM) is used to experimentally verified the effectiveness of the proposed technique.
