摘要
针对拦截弹末制导姿控脉冲发动机组合点火问题,利用吱呀轮优化(SWO)的导向式快速搜索特点,提出了一种基于SWO的点火逻辑优化控制算法。在分析脉冲发动机数学模型和点火控制约束条件的基础上,将脉冲发动机的组合点火问题转化为任务调度问题,并与贪心算法和遗传算法进行比较。仿真结果表明,该算法能够满足控制精度和实时性要求。
To solve the problem of optimizing the attitude control pulse engines combination in the terminal guidance of interceptor missiles,a new firing logic control algorithm based on Squeaky-Wheel Optimization（ SWO） was proposed. SWO was used to guide the search direction in large solution space. Firstly,mathematical models and firing control constraints of the engines were analyzed,and then the firing logic control problem was converted into task scheduling problem. At last,the proposed algorithm was compared with greedy algorithm and GA. Simulation results show that the method is able to meet the requirements of control accuracy and response speed.
