An advanced predictive current controller (APCC) based on deadbeat (DB) control theory for permanent magnet synchronous motor (PMSM) drives is proposed in this paper, where the optimum voltage vector is computed offline by solving an optimization problem. The optimum voltage vector along with a zero-voltage vector (ZVV) is applied to the motor under steady state condition to minimize ripples in the stator current. To achieve a fast dynamic response during the transient state, the voltage vector having the largest magnitude is applied for the complete duration of the control cycle. The phase of the voltage-vector is synchronized to control the components of the stator-current in a DB manner. In previously reported control methods, the two best voltage vectors (BVVs) are selected through enumeration and two independent duty ratios are calculated. However, this increases the computation complexity and computational time. The proposed APCC employs a novel approach in calculating the stator current references of PMSM using maximum torque per ampere (MTPA) control. The effectiveness of the proposed APCC is investigated and compared with some recently reported predictive current controllers. The APCC improves the performance of PMSM drive under steady and transient operation with lower total harmonics distortion (THD) of the stator current and better torque dynamics.

基于无差拍控制理论的高级预测电流控制器使永磁同步电机驱动的定子电流和转矩脉动最小化

本文提出了一种基于无差拍 (DB) 控制理论的用于永磁同步电机 (PMSM) 驱动器的高级预测电流控制器 (APCC)，其中通过求解优化问题离线计算最佳电压矢量。在稳态条件下将最佳电压矢量和零电压矢量 (ZVV) 应用于电机，以最大限度地减少定子电流中的纹波。为了在瞬态期间实现快速动态响应，在控制周期的整个持续时间内施加具有最大幅度的电压矢量。电压矢量的相位同步以 DB 方式控制定子电流的分量。在先前报道的控制方法中，通过枚举选择两个最佳电压矢量 (BVV) 并计算两个独立的占空比。然而，这增加了计算复杂度和计算时间。提议的 APCC 采用一种新颖的方法来计算 PMSM 的定子电流参考，使用每安培最大转矩 (MTPA) 控制。研究了提议的 APCC 的有效性，并与一些最近报道的预测电流控制器进行了比较。APCC 提高了 PMSM 驱动器在稳态和瞬态操作下的性能，定子电流的总谐波失真 (THD) 更低，扭矩动态更好。研究了提议的 APCC 的有效性，并与一些最近报道的预测电流控制器进行了比较。APCC 提高了 PMSM 驱动器在稳态和瞬态操作下的性能，定子电流的总谐波失真 (THD) 更低，扭矩动态更好。研究了提议的 APCC 的有效性，并与一些最近报道的预测电流控制器进行了比较。APCC 提高了 PMSM 驱动器在稳态和瞬态操作下的性能，定子电流的总谐波失真 (THD) 更低，扭矩动态更好。
