Vibrational feedback control of time delay systems

This paper applies vibrational feedback control to time-lag systems. Both stabilization and transient issues are discussed. An illustrative example is given which demonstrates that the proposed controller: 1) provides superior system gain and phase margin in comparison to time invariant controllers when applied correctly; 2) is not robust with respect to unknown delays; and 3) does not have zero placement capabilities, in the sense defined in the paper
