摘要
精细规划主要目的是实现飞控和火控的有效结合, 提出一套实现精细规划的理论框架。建立了威胁约束和火控边界条件约束模型, 给出了飞行器六自由度运动方程, 以运动方程为状态方程, 结合约束条件, 将精细规划问题转化为最优控制问题; 引入了主要应用于求解航天控制问题的勒让德伪谱法, 将最优控制问题转化为带约束的复杂非线性规划问题; 通过对CFSQP算法软件包的改进, 有效地减少了优化变量和约束条件数量, 使其能对大规模非线性规划问题快速寻优; 最后进行了实例仿真, 结果表明了该理论框架对实现精细规划的有效性。
Abstract
The main reason to realize detailed planning is to combine flight control with fire control.In the paper one theoretical framework for realizing detailed planning is given.Firstly the threat constraints and fire control border constraints models are built up a 6-DOF motion equation of the fighter was given and the detailed planning problem was changed into an optimal control problem based on the constrains by taking the motion equation as the state equation.Secondly Legendre Pseudospectral Method (LPM) was introduced to convert the optimal control problem into a Nonlinear Programming (NLP) problem with constrains.By improving the C Code Feasible Sequential Quadratic Programming (CFSQP) algorithm optimal results of the NLP problem could be quickly obtained.Simulation studies show that this framework works very well.
