由于实际的矢量控制效果对传动系统参数的敏感性，使其参数的在线跟踪有了很大的意义．提出了一种基于Ｈｏｐｆｉｅｌｄ神经网络的参数在线跟踪方法，并将在线跟踪结果用于参数突变５０％的交流传动系统磁通及转速控制器的自适应调整，得到了很好的仿真试验结果．
Due to the actual vector control of the sensitivity of the transmission system parameters, the parameters of the online tracking has great significance. A method of on-line parameter tracking based on Hopfield neural network is proposed, and the online tracking results are used to adaptively adjust the flux of the AC drive system and the speed controller with the mutation of 50%. A good simulation result is obtained.
