摘　　要：建立了高频响比例电磁铁的数学模型,并进行实验和仿真,结果表明:限制高频响电磁铁频宽的关键因素是比例电磁铁线圈的电感。通过在放大器中采用电流负反馈和PD校正环节两项措施有效克服了电磁铁线圈电感对比例电磁铁频宽的影响,提高了比例电磁铁的频宽。The mathematical model of the high response proportional solenoid was established, the experimental and simulation results show that the key factor of limiting the bandwidth of the high response proportional solenoid is the coil inductance. Through the use of current feedback and PD correct link in the amplifier, the effect of the coil inductance is overcome, thereby raising the proportional solenoid bandwidth.
