This paper presented a new optimal arbitrary time-delay filter (OAT) to cancel residual vibration in the system with vibratory mode. In this filter, the delay time can be given arbitrarily, which simplifies the design procedure. Robustness of the OAT filter can be improved by placing multiple zeros at the location of the system poles, which causes the penalty of system rise-time. The simulation results of mass-spring system demonstrate the effectiveness of the OAT filter.
