摘　　要：根据潜艇电力推进系统中六相同步电机(SSM)静止坐标系下的数学模型,针对其数学模型是一个多变量、非线性、强耦合的系统,利用矢量坐标变换,建立了更易于分析的旋转坐标系下的SSM数学模型。通过基于气隙磁场定向矢量控制的研究,保证气隙磁链恒定,就实现了SSM的磁通和转矩分别独立控制,仿真结果验证了模型的正确性和有效性,解决了多相电机的非线性和耦合性。According to mathematical model of submarine electric propulsion’s six-phase synchronous motor（SSM） based on stationary coordinate system,the model is multi-variable,nonlinear and tighten coupling.The suitable model is established under rotationary coordinate system,by using of vector coordinate transform.SSM’s magnetometive force and torque are carried out controlled respectively as long as air-gap-field invariance,through the research based on air-gapfield orientation vector control.The results show that the model is correctness and efficiency.It solves nonlinear and coupling of multiphase machine.
