中文说明：资源描述本算法是关于改进的粒子群算法优化bp神经网络，用于级联式变频器的故障诊断。有基本传统的bp神经网络算法，也有改进的粒子群优化神经网络算法，二者进行对比，取得了很好的效果，里面有例子数据。
English Description：
Application backgroundThis algorithm is about the improved particle swarm optimization algorithm to optimize the BP neural network, which is used for the fault diagnosis of cascade inverter. There are basic traditional BP neural network algorithm, there are also improved particle swarm optimization neural network algorithm, compared to the two, and achieved very good results, there are examples of data.
