首先建立翼伞六自由度的模型,利用最优控制理论,分别采用时间最优控制、能量最优控制以及相应的改进控制算法对翼伞空投控制技术进行比较研究。并提出以高度作为判断准则的系统归航方案,分别对比在不同的高度下,各控制方法的优缺点及适用性。在此基础上运用Simulink仿真验证不同高度下的最佳规划航迹,最终为实际翼伞的投放提供理论基础。
First of all, a model of six degrees of freedom of the parafoil is established. By using the optimal control theory, the time optimal control, the optimal energy control and the corresponding improved control algorithm are respectively used to compare the airdrop control technologies. And puts forward the system of home-to-home navigation with height as the criterion to compare the advantages and disadvantages of each control method and its applicability under different heights. On this basis, Simulink simulation is used to verify the optimal planning trajectory at different heights, and finally provides the theoretical basis for the actual deployment of the parafoil.
