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．
