An improved multi-node Newton iteration search method based on PSO

Abstract

When using the search algorithm to locate the vibrating target, Newton iteration method has strict requirement on the selection of initial value. To solve this problem, an improved Newton iterative search algorithm for vibration source location is proposed based on the analysis of Newton iterative search algorithm for multi-node co-location. The algorithm uses the estimation characteristics of POS algorithm to get the initial position of vibration source. Then the position of vibration target is determined by Newton iterative search method. The experimental results show that this method can effectively solve the problem of initial value selection of Newton iteration method and improve the localization accuracy of vibration source.
