摘要: This article proposes a new condition for the elimination of overflow oscillations in direct form digital filters with external interference. reduces effect interference to an ℋ∞ norm constraint. When there is no interference, this ensures exponential stability. Moreover, guarantees that state vector bounded if bounded. The proposed represented by linear matrix inequality (LMI), which can be checked easily standard numerical packages. A example given show effectiveness condition.
