基于复合结构元素的新型自适应形态滤波器设计
Design of a new adaptive morphological filter based on composite structure elements
摘要
Abstract
In view of the common noise interference in the signal acquisition of power system,an adaptive morphological filter using composite structure elements is proposed.The adaptive filter combines two or more structure elements as the composite structure element.The filtering error between the input and output signals is analyzed to determine the integral size of the composite structure element that can make the filtering effect reach the optimum.Then the parameters of the two elements of composite structure elements are adjusted according to the filtering error maximum principle for further optimization.Finally the optimal composite structure element is obtained.Simulation experiment is carried out on the adaptive filtering of the power signal containing random white noise.The results show that the proposed adaptive filter can accurately fred the optimal structure clement in the face of random noise.Compared with the traditional morphological filter using a single structure element,it has better filtering performance and also has a good application prospects.关键词
