| Bibliography: | Intermittent feedback;dead zone function;multi-dimensional Taylor network;dynamics model;system identifica-tion An integrated model of a dynamic system with herd behavior is difficult to be established because of its complex system structure, internal factors which influence each other, and involved human behaviors that are hard to predict. In this paper, a dynamics model based on intermittent feedback multidimensional Taylor network is proposed. According to the superposition of dead zone functions, the intermittent feedback caused by the crowd psychology of herd behavior is modeled, and the general dynamic equation suitable for common systems is established by combing the multi-dimensional Taylor network. The proposed method differs from the previous methods which start from individual studies of herd behavior, and establishes the integrated model containing herd behavior in terms of the data fluctuation which is externally characterized by the system. An example shows that the dynamics modeling method based |
