针对永磁同步电机(PMSM)的电流控制易受系统延迟、参数失配等因素影响，导致电流跟踪性能下降的问题，提出一种带延时补偿的自适应无差拍电流预测控制算法。在传统无差拍电流预测控制器(DPCC)基础上，针对参数失配引起电流跟踪性能下降的问题，改进了基于仿射投影算法的模型自适应补偿方法，设计了一种具有延时补偿的自适应电流控制算法。最后通过仿真试验，验证了所设计的带延时补偿的自适应无差拍电流预测控制对系统参数失配具有自适应补偿能力，可以有效消除系统延时的影响，提高电流环跟踪性能。

In order to solve the problem that current control of the permanent magnet synchronous motor (PMSM)is easily affected by factors such as system delay and parameter mismatch, which leads to the decrease of current tracking performance. Thus, an adaptive deadbeat current predictive control algorithm with delay compensation is proposed. Based on the traditional deadbeat predictive current control (DPCC), aiming at the problem of current performance degradation caused by parameter mismatch, the model adaptive compensation method based on affine projection algorithm is improved, and an adaptive current control algorithm with delay compensation is designed. Finally, the simulated experiments are carried out to verify the designed adaptive deadbeat current predictive control with delay compensation has adaptive compensation ability for system parameter mismatch, which can effectively eliminate the influence of system delay and improve the current loop tracking performance.
