液位控制BP模型的设计与仿真

Design and Simulation of BP Net in Water Level Control

基于MATLAB的神经网络工具箱与BP网络理论,介绍在MATLAB环境下发电厂液位控制BP模型的设计方法,并进行仿真试验,得出了预测模型的最优参数。仿真结果表明,此方法有效可行,可使非线性系统具有较好的跟踪性能。

Base on the neural network toolbox of MATLAB and the BP net theory, the modeling method for BP net is introduced,which is used in water control in the power plant. A Simulation experiment is made in MAT- LAB environment. The optimum parameters of the forecast model are also given. The simulation results show that the method is effective and available. It can enable the nonlinear system to have a better track precision.
