改进遗传模糊神经网络在舰船组合导航中的应用

Application of the Fuzzy Neural Networks Based on the Improved Genetic Algorithms in Ship Integrated Navigation System

由于舰船组合导航系统的实际运行环境比较恶劣,系统精确的数学模型及噪声的统计特性不易先验得到,而导致常规卡尔曼滤波器失效。尝试将改进遗传算法优化的模糊神经网络用于舰船组合导航系统中,仿真结果表明,提出的算法比较有效,并且精度和常规卡尔曼滤波算法相当。

Because it is more dicky that the real running environment of ship integrated navigation system, the exact mathematics model of system and the characteristic of yawp is difficult to get, and cause the routine kalman filter to lose efficiency. In this paper, the fuzzy neural networks based on the improved genetic algorithms was used in the system. The simulation results indicate that the algorithm is more effective, and the precision is equivalent to routine kalman filter.
