Vector control system for ship electric motor based on no-velocity sensor

本文根据用磁通观测器来估算磁通 ,以及用改进的 MRAS(模型参考自适应法 )来推算转速 ,构造了无速度传感器的异步电动机矢量控制系统结构 ,建立了控制系统的数学模型。仿真结果证明该系统的动静态特性良好 ,并具有磁通和转速的估算值 。

This paper uses flux monitoring to evaluate the flux and improved MRAS (model referring self-adapted method) to estimate rotate speed, builds asynchronous motor vector control structure of no-velocity sensor and mathematics model of control system. The simulation result shows that the system has good dynamic static feature, and the flux and rotating speed estimate value can well tack the practice value.
