摘　　要：导弹稳定控制参数设计是一个多参数组合优化问题,针对目前导弹稳定控制参数设计中依赖设计师的工程设计经验,有可能无法在全局范围内获得组合优化的控制器参数问题,研究基于改进遗传算法的导弹稳定控制参数自寻优设计方法。遗传算法随机性可增加个体多样性,使其具备找到全局最优解的能力,但同时随机操作会以一定概率将父代最优个体排除在种群之外。为此,针对遗传算法的随机性进行改进设计,通过引入确定性因子,使其在保留随机性的同时,增加一定程度的确定性,最终提高算法向最优解收敛的速度。将改进后的遗传算法应用于某型导弹稳定控制回路的参数自寻优设计中,六自由度仿真结果表明控制效果良好,验证了方法的正确性和可行性。The design of missile stability control parameters is a multi parameter combination optimization problem,aiming at the problem that the design of missile stability control parameters depends on designer’s engineering experience and may not be able to obtain the combinatorial optimization of controller parameters in the global scope,a self optimizing design method based on improved genetic algorithm is studied.The randomness of genetic algorithm makes individual more diversification,and makes it have the ability to search out global optimal solution,but at the same time,the random operation will exclude the optimal individuals of parent from the population with a certain probability.In this paper,randomness of genetic algorithm is improved,while a degree of certainty is increased by introducing a deterministic factor,and the convergence rate to optimal solution is improved finally.The improved genetic algorithm is applied to parameter’s self optimizing design of a certain missile stability control loop,the simulation results of six degrees of freedom are satisfactory,which verifies the correctness and feasibility of the method.
