| 摘 要： | 设计了一种免疫神经网络故障诊断方法,将神经网络权值进行编码作为抗体,将网络误差作为抗原,算法首先利用免疫算法的全局收敛特性,对网络权值进行全局搜索,然后再利用BP算法的局部搜索性能对网络权值进行局部搜索;以抽油机井为对象进行了仿真研究,并与BP神经网络故障诊断方法进行比较分析,表明免疫神经网络故障诊断方法能够有效避免陷入局部极小值的现象,并且在一定程度上加快了算法的运行速度。

| Abstract: | A fault diagnosis method based on immune neural network is proposed in this paper.In this method the weight of neural network is coded to be the antibody,and the error of the network is regarded as the antigen.Firstly the weight of the network is searched globally using immune algorithm with global convergent performance,Then searched locally using BP algorithm with local convergent performance.The simulations are done through the experiments of the pump-jack,and the diagnosis method proposed in this paper ... |
