Abstract

In this paper, we present the force ripple reduction method for iron-cored permanent magnet linear synchronous motors (PMLSMs), using position-dependent force constant. The iron-cored PMLSMs generate magnified force ripple due to magnetic saliency, which makes system vibrations and deteriorates the closed-loop performance. To suppress such motor force ripple, we propose the control method considering not only geometry-driven ripple (GDR) but also current-driven ripple (CDR) which is investigated in detail how it can be generated in PMLSMs. We also present the identification method for both current-driven force (CDF) and geometry-driven ripple in simple experimental setup without additional equipment, and it is validated experimentally with NRMSE (peak-to-peak normalized root mean square error) of 4.74 % and 1.01 % for CDF and GDR, respectively. Using the identified motor parameters, the force ripple is reduced by 91.5 % and 86.9 % in RMS and peak-to-peak value, without sacrificing the motor thrust and with small additional power consumption.
