| 摘 要： | 针对永磁接触器提出了一种弱磁控制策略,实现合闸过程的智能化闭环控制,使其动态吸力和反力达到良好配合.结合磁路和电路模型,实现了动铁心实时位移信号的无位置传感器检测.耦合电压平衡方程和机械运动方程,建立了弱磁控制策略下合闸过程的动态数学模型,并采用4阶龙格-库塔法仿真了合闸动态过程.实验结果表明,通过调整和优化正、反向PWM占空比,可实现线圈正、反向电流的有效控制,由此调节动触头和动铁心的运动速度,使触头一、二次弹跳明显减少.仿真与实验结果比较吻合.

| Abstract: | A flux-weakening control strategy for permanent magnet(PM) contactors was proposed,which realized the intelligent closed-loop control during making process and made the dynamic attraction force match with the reaction force well.A sensorless detection of real-time displacement signal of the moving iron core was realized by combining magnetic circuit and electric circuit models.Dynamic mathematical model for making process under the flux-weakening control strategy was established by coupling the voltage equi... |
