N2 - The detent force of permanent magnet linear machine (PMLM) is the main reason causing thrust ripple. To solve this problem, a detent force suppression strategy based on a third-order extended state observer (ESO) is proposed in this paper. Firstly, the PMLM structure is presented and the detent force of this machine is obtained and analyzed based on finite element method (FEM). Then the structure of the third-order ESO is presented and the stability of the proposed ESO is analyzed. Finally, simulation verification is carried out, and the simulation results prove the effectiveness of the proposed strategy in terms of ripple suppression.
