| 摘 要： | 基于经典的POWELL寻优算法和粒子群混合算法,针对航行体的操纵运动数学模型开展智能辨识研究。该方法能够很好地调整算法的全局与局部搜索能力之间的平衡,有效地提高辨识的精度和速度。采用该方法,利用航行体操纵性试验结果,对航行体操纵运动方程系数进行了辨识研究,并用辨识的数学模型进行了水面Z形操纵仿真。仿真结果表明,该方法具有很好的全局收敛性和稳定性。

| Abstract: | This paper proposes an identification method for vehicle's maneuvering equation based on the Powell search method and the particle swarm optimization(PSO) hybrid algorithm.The method can not only adjust the balance between global and local exploration suitably,but also raise the accuracy and speed effectively.According to turning model test data,a set of vehicle's maneuvering equation coefficient is identified by the method,and applying the identification model in the simulation of zig zag test on water.The... |
