本文通过四元数船域（QSD）模型结构，提出了一种新的动态四元数船域（DQSD）模型分析框架。与以往的船舶领域不同，所提出的DQSD模型能够捕捉船舶领域的基本主观性和客观性。具体而言，其显著特点如下：（1）DQSD模型由船舶、人和环境三个独立的子模型集成而成，这三个子模型分别由船舶操纵性、驾驶员状态和航行环境决定。(2)根据MMG型船舶运动模型推导出的船舶操纵性，建立了船舶子模型，确定了DQSD尺度。(3)提出了一种新的导航员可靠性模型来实现人的子模型，该模型定义了以导航员能力、生理和心理状态为输入变量的船舶域形状。(4)此外，能见度，风力，波浪和交通拥挤被纳入环境子模型，用于放大或缩小DQSD型船舶域。最后，利用著名的Esso Osaka油轮模型对各种典型的静态和动态情况进行了仿真研究，并进行了全面的对比分析。仿真结果表明，DQSD模型可以捕捉到船舶领域的关键动态，无疑是有效的，并优于以往的船舶领域的性能和精度上级。
In this paper, a novel analytical framework for Dynamic Quaternion Ship Domain (DQSD) models has been initially proposed via the Quaternion Ship Domain (QSD) model structure. Unlike previous ship domains, the proposed DQSD model is able to capture essential subjectivity and objectivity of ship domains. To be specific, the significant characteristics are as follows: (1) The proposed DQSD model is integrated by three independent submodels of ship, human and circumstance, which are determined by ship manoeuvrability, navigator's states, and navigation circumstance, respectively.(2) The ship manoeuvrability derived from the MMG-type ship motion model is employed to establish the ship submodel which identifies the DQSD scale.(3) A novel navigator reliability model is proposed to realize the human submodel which defines the ship domain shape with navigator ability, physical and mental states being input variables.(4) In addition, visibility, wind force, wave and traffic congestion are incorporated into the circumstance submodel which is employed to zoom in or out of the DQSD-type ship domain. Finally, the well-known Esso Osaka tanker model is used to conduct simulation studies on various typical stationary and dynamic situations, and comparative investigations with each other have been comprehensively analysed. Simulation results demonstrate that the DQSD model can capture critical dynamics of ship domains and undoubtedly be effective and superior to previous ship domains in terms of performance and accuracy.
