Abstract：To address the issue of parameter mismatch in traditional deadbeat predictive current control for permanent magnet-asisted synchronous reluctance motors （PMSynRM），which leads to current divergence and significant currnt fluctuations during operation，a deadbeat predictive current control algorithm based on a linear extended state observer （LESO） was proposed. Building upon the traditional deadbeat predictive current control algorithm，a linear extended state observer was introduced to estimate the total disturbance in real-time，and the estimated disturbance was fed back to the deadbeat controler for feedforward compensation. Based on the mathematical model of the PMSynRM，a mathematical model of the motor itself is established to simulate and validate the proposed algorithm.Finaly，experimental verification was conducted on a platform centered around the TMS32OF28335 controllr.Simulation and experimental results demonstrate that，compared to traditional deadbeat predictive current control，the proposed method exhibits better robustness and tracking accuracy under parameter mismatch conditions.

Keywords： permanent magnet-assisted synchronous reluctance motor；linear state observer; deadbeat predictive current control； robustness
