Abstract：Aiming at the problem of disturbance rejection in permanent magnet synchronous motor (PMSM) control, a multi-variable linear extended state observer (LESO) was used to estimate the state, load disturbance and uncertainty of the system. The effects of the parameter selection of LESO on the convergence, rapidity, robustness of interference and noise were systematically analyzed in frequency domain. The steps of LESO parameter tuning for PMSM were also given. Compared with the existing methods, the parameter selection range of LESO is broadened and the observation effect on PMSM state is improved, which lays a good foundation for improving the control quality. The results have theoretical value and engineering practice guiding significance. Simulation and experimental results verified the effectiveness of the conclusions.
