基于双DSP在交流位置伺服系统的小波神经网络控制

Wavelet Neural Network Control of AC Position Servo System Based on Dual DSP

采用双DSP设计完成了交流位置伺服系统的神经网络实时控制系统,其中一片DSP作为系统的小波神经网络控制器(NNC),另一片DSP作为系统的BP神经网络在线辨识器(NNI)。由NNI对被控对象进行在线辨识的基础上,通过对NNC的权系进行实时调整,使系统具有自适应性。通过对交流位置伺服系统的控制实验,验证了本系统的实用性。

This paper uses the dual DSP, one as wavelet neural network controller（NNC） ,the other as BP neural network identifier （NNI） to design the AC position servo neural network realtime control system.Due to the real time adjustment of NNC weight and the NNI on-line identification of the controlled object, the system is more available. Its practical practicability is verified by the control sim- ulation of AC position servo system.
