Design of unascertained information digital filter and its application
Luo Zhongliang · Journal of Transducer Technology · 2002
Due to the low-pass property of traditional digital filter,a contradiction between fast tracing ability and anti-interference ability is generated,and the traditional way also lacks the ability of handling abrupt disturbance as well as variation of measuring true value.After defining the support interval and support probability of unascertained information from a statistical view,a digital filter algorithm that quite suits intelligent instruments is brought up.Some data test,show that this algorithm excels in both anti-interference and fast tracing, which reflects its correctness and efficiency.
