摘要: 采用了零点配置方法来设计具有强鲁棒性的时滞滤波器,消除小阻尼不确定性系统的残留振荡。在系统极点附近配置多个滤波器零点,通过建立离散传递函数来得到时滞滤波器方程,设计简单,减少了计算量。该方法在起重机载荷防摆控制中得到了很好的应用,能够有效地消除载荷的摆动,对缆绳长度的变化具有很好的鲁棒性。

Abstract: A new technique is proposed for deriving robust time delay filter using zero-placement in the discrete domain to reduce residual vibration in the uncertain system. Unlike previous derivation, this method places some zeros around the system poles and leads to construct discrete transfer function to meet requirements on filter performance. This derivation is verified with anti-sway control of cranes.
