基于BP神经网络模糊励磁控制器的研究

Research on fuzzy PID Excitation Controller Based on the BP Neural Network

针对常规型PID作用下的控制器参数改变的不确定性,将BP-NN网络技术和Fuzzy模糊理论引进PID式控制器中,组成了BP神经网络技术的模糊规则的PID式控制器。经过对数学模型的仿真实例的对照和研究,发现基于BP神经网络和模糊技术的PID控制器能改善动态性能,控制效果好。

For conventional type under the action of the PID controller parameter change of uncertainty,the BP- NN network technology and Fuzzy theory to introduce Fuzzy PID controller,Fuzzy rules of the BP neural network technology of the PID controller. Through simu-lation examples of mathematical model of comparison and research,found that based on BP neural network and PID controller can improve the dynamic performance of fuzzy technology,good control effect.
