Abstract: Reasonably combining the parallel structure of genetic algorithm with the controllable jumping property of simulated annealing, a class of effective and general hybrid optimization strategy is proposed and applied t o estimate the parameters of various kinds of models. - 摘要为解决高维复杂函数的优化问题，克服标准粒子群算法早熟收敛、局部搜索能力弱等缺点，在标准粒子群优化算法中融合了遗传算法的设计思想，提出了一种新颖的混合粒子群算法。
Abstract A new hybrid particle swarm optimization combined with genetic algorithm was proposed in order to solve complex questions with high dimensions and overcome prematurity and the weak ability of local search. - 提出了将模拟退火算法融合于遗传算法中的组合方案,对传动装置监测信号小波能量谱进行编码,以克服利用BP算法进行样本训练时网络可能会陷入局部极小点的缺点.以某型传动装置监测信号的小波能量谱为训练样本,识别传动装置带有缺损的齿轮的故障征兆.计算结果表明,组合方案能够提高神经网络训练效率和故障征兆识别精度.
A method for identifying the gear fault of the transmission system is presented,where the simulated annealing algorithm and genetic algorithm are combined in order to prevent the BP network going into the local minimum points during the training work.By using the wavelet energy spectrum of the signal measured from a certain transmission system,the symptom of the gears with damnification is detected.The results show that both the training efficient and the identifying precision are increased obviously.
