An Improved Digital Filtering Method Based on First Order Inertia Link

摘要

Digitalization of low-pass filter produced from first-order inertia link is carried out firstly in this paper. Then an improved algorithm is proposed to achieve better low-pass characteristics by smoothing the first n-part data and using the smoothed data instead of n-1 based on the first step. At last, through the detailed numerical simulation analysis, the correctness and validity of the proposed improved filter design method are verified.
