PERPENDICULAR IMPACT GUIDANCE LAW BASED ON GENETIC ALGORITHM

Guidance law is the core question for a torpedo in fulfilling its precision homing and executing its action. The paper lays emphasis on the question about the genetic algorithm applied in the guidance law of a torpedo. The feasibility and superiority of genetic algorithm in torpedo perpendicular impact guidance law were studied. Gradual change in the angle of lead in torpedo homing guidance law was proposed on the basis of the character of genetic algorithm, and corresponding simulation was made. It is shown that the guidance based on genetic algorithm has a rapid response and robustness feature. The question of astringency of guidance law is also solved, so it has a prospective engineering utility.
