摘要:
应用遗传算法解决液体火箭发动机减损控制律综合分析这个典型的多目标优化 问题。可以解决传统优化方法在该问题中的局限性。分析了遗传算法在解决液体火箭发动机 减损控制律综合分析中的具体应用问题，如编码方案、种群设定、适应度函数设计、约束条 件处理、选择机制、交叉与变异操作以及遗传算法有关参数的确定等，分别给出了可行的取 值参考范围。应用SPEA进行了仿真计算，结果表明遗传算法在综合分析减损控制律时是有 效的．为智能技术在液体火箭发动机减损控制中的应用提供了方法探索。
Abstract:
Analysis and synthesis of the Damage-mitigating Control(DMC)law by applying the genetic algorithm for the Liquid-propellant Rocket Engine(LRE)are presented．The genetic algorithm can overcome the demerits of the classical optimizations in solving the DMC law，a typical multi-objective optimization，for the LRE．The related parameters with the genetic algorithm，such as coding scheme，population size，fitness function，constraints，selection operator，crossover operator and mutation operator，are clarified to analyze and synthesize the DMC law for the LRE in this paper． The feasible value domains of each parameter are obtained．The results indicate that the genetic algorithm is effective for analyzing and synthesizing the DMC law by employing the SPEA(Strength Pareto Evolutionary Algorithm)．This paper is a methodology research for applying the intelligent technology to the DMC of the LRE．
