  • Abstract
    It is shown in this note that for SISO system under l2 disturbances, when data commute approximately with the shift the optimal interpolation (over all linear time-varying interpolants) can be approximated by the supreme of the frozen-time Hankel norms. This confirms the intuition that the frozen-time constructed optimal or suboptimal interpolants are in fact nearly optimal when data vary slowly.
