摘要
遗传优化算法具有搜索全局最优解的功能,将该算法应用到舰载导弹垂直发射中,并验证发射角度的控制效果。根据能量谱密度函数,计算舰船摇摆运动谱;结合线弹性变形原理,提取间隙碰撞和摩擦力影响数值,构建垂直发射力学模型;状态估计函数评价舰载导弹发生状态,遗传优化算法控制垂直发射角度。与不同算法的应用效果相比,研究的算法控制下,舰载导弹在发射筒内的水平位移、垂直位移最小,能够更有力地约束垂直发射角度。
Genetic optimization algorithm has the function of searching the global optimal solution.The algorithm is applied to the vertical launch of shipborne missile,and the launch angle control effect is verified.According to the energy spectrum density function,the ship swaying motion spectrum is calculated;Based on the principle of linear elastic deformation,the effects of clearance collision and friction are extracted,and the vertical launching mechanical model is constructed;The state estimation function evaluates the occurrence state of shipborne missile,and the genetic optimization algorithm controls the vertical launching angle.Compared with the application effect of different algorithms,the horizontal displacement and vertical displacement of the shipborne missile in the launcher are the minimum under the control of the algorithm,which can more effectively constrain the vertical launch angle.
