This paper applies vibrational f d back control to time lag systems. Both stabiliiation and transient h u e s are d k m s e d . An illustrative example is given which demonstrates that the proposed controller: 1) provides s-erior system gain and phase margin in comparison to time invariant controllers when applied cop rectly, 2) is not robust with respect to unknown delays and 3) does not have zero placement capabilities, in the sense defined i n the paper.
