摘要
针对粒子群优化算法(PSO)无法处理反求问题中的病态问题,基于粒子群优化算法,通过遗传算法对粒子群优化算法进行改进,提出一种改进的粒子群优化算法(GAPSO),通过载荷识别对该方法进行验证,并应用于静态载荷识别和动态载荷识别算例中。研究结果表明:改进后的粒子群优化算法既能使粒子群优化算法处理病态问题,又提高了反求问题的求解精度。
Considering that particle swarm optimization algorithm(PSO)cannot deal with ill-posed problem,an improved particle swarm optimization algorithm(GAPSO)was proposed by genetic algorithm based on particle swarm optimization.This method was verified by common inversion problems such as load identification.Finally,the improved optimization algorithm was applied in static load identification and dynamic load identification.The results show that the improved particle swarm optimization algorithm can not only solve ill-posed problems,but also improve the accuracy of inverse problem.
