摘　　要：内置式永磁同步电机(IPM)以其能量密度大,调速范围广的特点在插入式混合动力电动车(PHEV)上得到广泛的应用。该文针对传统矢量控制两电流调节器高速调节(TCC)困难的问题,给出了一种单电流调节器(SCC),并提出一种根据反馈的定子电流和转速提高SCC效率和稳定性的方法即可调节单电流调节器(ASCC)。利用电机稳态数学模型,推导出q轴及其解耦分量可由d轴电流决定的数学表达式,通过在矢量图上对比最大电流/转矩(MTPA)及理想控制曲线,说明了ASCC的有效性。仿真和实验结果证明所设计的控制器具有很好的效率和应用前景。IPM（Interior Permanent Magnet Synchronous Machines）have the advantages in the field of power density,wide-range speed,as a result many auto corporations hires it for PHEV（Plug-in Hybrid Electrical Vehicle）.In the field of PHEV,wide-range speed reminding invariable power is very important,but normal TCC（Two Current controller）faces the problem of controlling stability and lower IGBT current efficiency.In this paper,first introduced a new structure named SCC（Single Current controller）,and next developed an ASCC（Adaptive Single Current controller）for getting a better current efficiency.With the help of steady IPM model,educed the relation between and,decoupling part.The experimented and simulation results show that ASCC controller has a good performance and practical use prospects.
