【摘要】 提出一种在不增加分数阶微分滤波器复杂度的前提下,能有效提高分数阶微分滤波器性能的方法。该方法利用几种基于典型微分算子的分数阶微分滤波器之间的互补性,通过相互内插结合的方式,用于提高ⅡR分数阶数字滤波器的性能。改进后的分数阶微分滤波器频率响应更接近理想分数阶微分滤波器,表明所提方法的有效性。更多还原

【Abstract】 This paper proposes a design method which can improve the performance of fractional order differential filter obviously under the premise of not increasing the structure complexity of the filter.This scheme which bases on mutually compensatory characters of typical differentiator and uses interpolated method to improve performance of ⅡR digital fractional differential filter.The improved frequency response of fractional differential filter is more close to ideal fractional differential filter,it indicates the validity of proposed method.更多还原
