提出了一种新的永磁接触器弱磁控制策略。通过动态吸引力和反作用力的匹配，使动铁在合闸过程中的终端速度和碰撞能量显著降低。通过检测合闸电压和合闸电流来估计动铁位移。建立了四种激励情况下的动态数学模型。采用有限元法对磁链和磁吸力进行了预测，并采用四阶龙格-库塔算法对合闸过程进行了仿真。实验进行了250 A的原型与智能控制单元，以验证所提出的控制策略。
A new flux-weakening control strategy for permanent magnet contactors is proposed. By matching the dynamic attraction force and the antiforce, the terminal velocity and collision energy of the movable iron in the closing process are significantly reduced. The movable iron displacement is estimated by detecting the closing voltage and current with the proposed control. A dynamic mathematical model is also established under four kinds of excitation scenarios. The attraction force and flux linkage are predicted by finite element method and the dynamics of the closing process is simulated using the 4th-order Runge-Kutta algorithm. Experiments are carried out on a 250A prototype with an intelligent control unit to verify the proposed control strategy.
