摘要根据非线性动力学理论和铁磁谐振的特性, 提出一种新的抑制铁磁谐振的概念——用同步脉冲控制理论使过电压系统与正常工作的系统同步。通过Matlab软件仿真计算, 表明该方法能有效实现谐振系统与正常系统的快速同步, 大幅降低控制能量, 并突破以往研究仅抑制混沌形态过电压的局限。同时, 首次应用ATP-EMTP软件对采用脉冲抑制铁磁谐振的方法进行仿真, 仿真结果同样验证了该理论的有效性。

Abstract：A new concept of suppressing ferroresonance was proposed after analyzing the nonlinear dynamics and characteristics of ferroresonance. In this concept, a method of feedback impulsive chaotic synchronization was utilized to synchronize the ferroresonance system with normal system. The quickness and energy-efficiency of this method was proved by simulation in Matlab, which was also proved by ATP-EMTP for the first time. In addition, this method is also useful to the non-chaotic systems which have never been studied before.

Key words： Ferroresonance chaos overvoltage synchronization feedback impulse parameter mismatched
