Reduced-Order H ∞ Filter Design for Singular Fractional-Order Systems.

This paper investigates the problem of reduced-order H ∞ filter design for singular fractional-order systems with order 0 < α < 1 . It provides necessary and sufficient conditions for designs of both reduced-order H ∞ filters and zeroth-order H ∞ filters. When reduced to special cases, the present results are shown to include those in recent works as special cases. Illustrative examples are presented to demonstrate the effectiveness of the results.
