降低固体推进剂特征信号的改进粒子群算法
Improved particle swarm algorithm to lower characteristic signal of solid propellant
摘要
Abstract
Characteristic signal of solid propellant combustion more and more becomes an important factor to restrict missile stealth characteristics and guidance precision development. In order to solve the problem of long formulation design cycle to reduce the characteristic signal, which is caused by traditional experimental method, Particle Swarm Optimization Algorithm(PSOA)is studied to find the optimal design scheme of solid propellant formulations to reduce characteristic signal. In the process, the rejection method, the penalty function method and the strategy of keeping population diversity are used to improve standard PSOA properly. It solves the nonlinear constraint problem, overcomes the defects of algorithm to fall into local optimum easily and improves global search ability. Establishment of the formulation optimi-zation model and simulation results show that in the aspect of reducing characteristic signal, improved PSOA is superior to some other intelligent algorithms, such as, improved genetic algorithm, standard particle swarm optimization and so on,and it can also shorten the formulation design cycle.关键词
