舰船多相永磁同步电机推进系统容错控制研究

Research on fault tolerant control of marine multi_phase permanent synchronous motors propulsion system

根据综合矢量方法 ,提出了一种有效的容错控制方法 ,根据多相PMSM电力推进系统缺相故障后绕组的非对称分布的特点 ,提出了形成圆形磁场的各相定子电流的幅值和相位条件 ,并对容错控制的方法进行了仿真。

A new efficient fault tolerant control is proposed on the basis of space vector method.According to the characters of asymmetric distribution when stator phrase failure occurs in the PMSM propulsion,different phrase current value and its phrase condition are brought forward,which contribute to the round magnetic field,The simulations on the fault tolerant control are also given.
