摘　　要：惯性测量单元(IMU)用来为舰载武器系统提供准确的姿态并实时监测舰船甲板的变形,对其数目和位置进行优化具有重要的实用价值。提出了多IMU优化布局的原则,建立了舰载IMU优化布局的数学模型,采用遗传算法对IMU的布局进行了优化求解。仿真结果表明,舰载IMU的布局是影响甲板变形估计精度的一个重要因素,通过对IMU的布局进行优化,减少了舰载武器系统所需IMU的数量;利用优化布局后IMU的输出信息对全舰甲板变形进行估计,估计精度有很大提高。IMU is used to provide shipbome weapon systems with accurate attitudes and to monitor deck deformation real time. It is worth researching further to optimize the location and number of IMU. The paper presented the principle of multi-IMU layout optimization and created its mathematical model. The IMU layout optimization was solved using Genetic Algorithm. The simulation results show that the number of IMU for shipbome weapon systems is decreased. The layout of shipborne IMU is an important factor that impacts the estimation accuracy of deck deformation, and the estimation accuracy is improved greatly by IMU layout ootimization.
