A new technique for deriving high robust time delay filter using zero placement was proposed in discrete time domain to reduce residual vibration in an uncertain system. Unlike the previous derivation, this method places some zeros around the system poles and leads to construct discrete transfer function to meet the requirements on filter performance. The simulation results of crane demonstrate the effectiveness of this new method.
