通过严格的理论分析和数学计算，建立了同步电动机在同步坐标系中E—L方程形式的数学模型，给出了磁场矢量控制的基本控制目标。以这些模型为基础，研究并设计了在负载转矩为任意时变未知情形下同步电动机时变转矩（转速、位置）的无源性渐近跟踪控制器。在实现机械控制目标的同时考虑并实现了对磁场方向和磁场幅值的控制，即同时实现了磁场矢量控制。

By strict analysis and calculation, the same two types of synchronous motor models as induction motors are established in various reference coordinates. Based on the established model in the synchronous rotating coordinates, the passivity based controller of synchronous motor is designed in case of time--varying and unknown load torque. In order to carry out the torque （rotor velocity and rotor position）tracking control, the magnetic amplitude and angle asymptotic tracking control are established simultaneously.
