摘要: 针对同步磁阻电机型控制棒驱动机构（CRDM）电磁高度耦合难以对输出力矩进行有效线性调节的问题，研究了同步磁阻电机型CRDM的矢量控制技术。将同步磁阻电机CRDM的数学模型映射至同步旋转坐标系内，对输出电磁力矩与磁链进行解耦。通过励磁电流与力矩电流的独立调节，实现输出力矩的线性控制。利用MATLAB/SIMULINK搭建了同步磁阻电机型CRDM的矢量控制模型，对控制方案进行验证。仿真结果表明，本研究的控制方案具有更优的响应速度、稳态精度以及平稳性。

Abstract: Aiming at the problem that the synchronous reluctance motor control rod drive mechanism (CRDM) is highly electromagnetically coupled and it is difficult to effectively adjust the output torque linearly, this paper studies the vector control technology of the synchronous reluctance motor CRDM. The mathematical model of the synchronous reluctance motor of the CRDM is mapped into the synchronous rotating coordinate system, and the output electromagnetic torque and the flux linkage are decoupled. And the excitation current and the torque current are independently adjusted to realize the linear control of the output torque. The vector control model of the synchronous reluctance motor CRDM was built using MATLAB/SIMULINK to verify the control scheme. The simulation results show that the control scheme of this research has better response speed, steady-state accuracy and stability.-
