Particle filter (PF) serves as an effective method applied to the fault diagnosis of nonlinear and non-Gaussian systems. However, the result of state estimation is influenced by the particle impoverishment problem which is common in the typical PF algorithm. Based on the analysis of the PF algorithm, the general particle impoverishment problem is attributed to the deficiency of particle diversity...
Practical production systems are usually complex, nonlinear and non-Gaussian. Different from some other fault diagnosis methods, particle filter can applied to nonlinear and non-Gaussian systems effectively. The particle impoverishment problem exists in the traditional particle filter algorithm, which influences the results of state estimation. In this paper, we conclude that the general particle...
Object matching is an important issue for machine vision, object recognition and image analysis. A Hausdorff distance is one of commonly used measures for object matching because it is simple and insensitive to changes of image characteristics. But the conventional Hausdorff distances require high computational complexity and are not suited to the practical applications. In this work, we propose a...
Quantitative characterization models of oil increment and water-cut change in polymer flooding called Hou's models are established in the paper. The mathematic models are concise and characteristic parameters have specific physical meanings and are easy to determine. Automatic solution method based on real-coded genetic algorithm (GA) is presented. Based on numerical simulation of polymer flooding,...
