摘　　要：提出了一种鲁棒设计方法——容许幅度法。在陷波频率附近按照一定的频率偏移 ,选择数个陷波频率分别设计时滞陷波器 ,然后将各个陷波器级联 ,设计出具有多个波头的多峰容许幅度时滞陷波器 ,大大提高了控制系统的鲁棒性。This paper presents a robust method to design time delay notch filter with feasible magnitude in frequency response. Several frequency offset are selected near the system modal frequency to design time delay notch filters respectively, then convolved in series. The resulted multi-hump time notch filter with feasible magnitude improves robustness greatly. At last, the effectiveness of the proposed method is illustrated by the application to crane system during load hoisting.
