摘　　要：传统永磁同步电机(permanent magnet synchronous motor,PMSM)因恒定永磁励磁而扩速困难;新型双定子交替极永磁(dual-stator consequent-pole permanent magnet,DSCPPM)电机,兼具双定子及混合励磁电机优势而更适合高转矩宽调速应用。此外,电流解耦控制器及电流分配策略是实现电机宽调速控制的关键。因此,该文提出一种适合DSCPPM的内模电流控制器,通过滤波带宽的单参数设计,实现复杂电机模型电流解耦控制及动态调节,显著降低多电流控制器参数整定难度。同时,该文提出一种宽调速电流分配策略,其将电机全速域分为恒转矩区、弱磁一区以及弱磁二区,分别以最大转矩电流比、最短路径以及最优弱磁电流为目标对电流轨迹进行优化,来实现电机宽调速运行。最后,通过样机实验结果验证所提控制策略的有效性。The traditional permanent magnet synchronous motor(PMSM)is difficult to expand due to the constant permanent magnet excitation.The novel dual-stator consequent-pole permanent magnet(DSCPPM)motor combines the advantages of the dual-stator motor and the hybrid excitation synchronous motor(HESM),making it more suitable for high torque wide speed regulation applications.In addition,the current decoupling controller and the current distribution strategy are critical in realizing the wide speed control of the motor.Therefore,an internal model current controller suitable for DSCPPM is proposed in this paper.Through the single-parameter design of the filter bandwidth,the current decoupling control and dynamic adjustment of complex motor models are realized,which greatly reduces the difficulty of parameter tuning of multi-current controllers.In addition,this paper proposes a wide-speed current distribution strategy.In this paper,a wide-speed current distribution strategy is proposed,which divides the full-speed domain into a constant torque region,a flux-weakening region I and region II.The current trajectory is optimized with the current amplitude,the shortest path and the optimal flux-weakening current.Finally,the effectiveness of the proposed control strategy is verified by the experimental results of the prototype.
