The model is sensitive to disturbance frequency which is an essential factor for rock burst occurrence, and is insensitive to disturbance amplitude.

该模型对扰动频率非常敏感，扰动频率满足一定条件是动力扰动下洞室发生层裂屈曲岩爆的必要条件；

Frequency Selective Filter (FS f) is utilized to design feedback controller in frequency do-main. For each disturbance frequency, there are only two real coefficients to be tuned.

使用频率选择滤波方法在频域设计反馈控制器，对每个干扰频率，仅需调节两个实系数。
