| 摘 要： | 为测量大型舰船甲板的变形，对甲板变形引起的局部姿态误差进行补偿，设计了基于多IMU数据融合的全舰统一姿态基准测量系统．提出了甲板变形测量方法，建立了IMU布局优化数学模型，并运用遗传算法对IMU的布局进行了优化求解．仿真结果表明，建立全舰统一姿态基准测量系统是测量舰船甲板变形的有效办法，利用布局优化后IMU的输出信息进行全舰甲板变形估计，估计精度优于2.3arcmin，并能减少舰载武器系统所需IMU的数量．

| Abstract: | Based on multi-IMU data fusion,a method of deformation measurement was proposed to compensate the local attitude error resulting from deck deformation.A model of multi-IMU layout optimization was presented.The uniform atti-tude reference measurement system of whole ship was developed and the IMU layout optimization was solved using genetic algorithm.Simulation results show that by processing the output signals of the IMU used in the uniform attitude reference measurement system,it is feasible to realize real-time estimation of deck deformation.The prediction error is less than 2.3 arcmin through IMU layout optimization,and the number of IMU for shipborne weapon systems decreases. |
