水下高速超空泡射弹建模与最优控制的中期报告 摘要： 本文主要介绍水下高速超空泡射弹建模及其最优控制方案的中期报告。针对该问题，首先建立了水下高速超空泡射弹的非线性动力学模型；然后利用最优控制理论，设计了基于状态反馈的最优控制器，将水下高速超空泡射弹的控制问题转化为求解阶段性Riccati方程组的问题。最后，对所设计的最优控制器进行了数值仿真，并对仿真结果进行了分析。 关键词： 水下高速超空泡射弹；建模；最优控制；状态反馈；Riccati方程组 Abstract: This paper presents a mid-term report on the modeling and optimal control of underwater high-speed supercavitating projectiles. Firstly, a non-linear dynamic model of the underwater high-speed supercavitating projectile was established. Then, based on the optimal control theory, a state feedback optimal controller was designed to transform the control problem of the underwater high-speed supercavitating projectile into the problem of solving stage Riccati equations. Finally, numerical simulations were conducted to validate the designed optimal controller, and the simulation results were analyzed.
