摘要
为了更好地对电磁兼容进行预测,提出采用人工神经网络的方法。传统的BP神经网络易于陷入局部最优,因此采用粒子群算法对网络权值进行优化。以平行线间电磁耦合干扰为具体算例,证明本算法的预测结果的均方误差仅有10-4数量级。因此,使用PSO优化网络权值的方法有效,且神经网络模型能准确预测电磁兼容。
In order to predict the electromagnetic compatibility more effectively, an improved method based on artificial neural network was proposed. Due to the fact that BP neural network was inclined to be trapped in local extrama, a novel network--particle swarm optimization based neural network--was proposed in this paper to solve the above shortcoming. The specific example on electromagnetie coupling interference between two parallel wires demonstrates the median square error of the prediction is more or less only 10^-4 order of magnitude. Thus, this PSO-based neural network is effective, and our model can predict electromagnetic compatibility accurately.
