摘　　要：为了确保电网的安全运行,提出一种抑制铁磁谐振混沌现象的新方法。该方法采用广义投影同步理论,设计了合适的反馈控制器,实现了铁磁谐振混沌系统对目标系统进行成比例的同步控制。无论目标系统是否在正常的工况下运行,当选取适当的缩放因子时,该方法都能将铁磁谐振混沌系统工作电压限制在正常范围内。而且根据系统的实际需要,还能够实现混沌系统与目标系统之间的同相位或反相位的同步追踪控制。仿真结果表明,该方法的有效性与理论分析一致,能够有效抑制铁磁谐振过电压混沌现象。In order to ensure the safe operation of the power grid,this paper proposes a new method of inhibiting the chaotic phenomenon of ferromagnetic resonance,which utilizes the generalized projective synchronization theory,designs an appropriate feedback controller,and realizes the proportional synchronous control between the ferromagnetic resonance chaotic system and the target system.Whether the target system operates in the normal working condition or not,the method can limit the working voltage of the ferromagnetic resonance chaotic system in a normal range when selecting an appropriate scaling factor.According to the actual needs of the original system,the method can also realize in-phase or anti-phase synchronous tracking control between the chaotic system and the target system.The simulation results show that the method is effective and the results accord with the theoretical analysis.That is,it can inhibit the overvoltage chaotic phenomenon of ferromagnetic resonance effectively.
