【摘要】 神经网络具有很强的自学习和自适应能力,对于大滞后、非线性的复杂系统有较好的控制效果。针对水处理过程中系统环境不断变化,特别是流量有较大、频繁变化的情况下,在FCD絮凝控制系统的基础上,提出了神经网络控制方法,解决了混凝控制中的目标等效直径动态确定问题。实际运行表明,该方法取得了很好的控制效果,具有广阔的应用前景。更多还原

【Abstract】 Neural network is of good ability of self-learning and self-adapting,therefore,it has better control effectness for nonlinear large time-delay complex system.By analyzing the different situation in water supply,especially the sudden change of flow,raises the method of neural network based on flocculation image manipulation,resolve the problem that the target-value of equivalent diameter is always uncertain.The application shows that the method can obtain satisfactory control,and has broad application foreground.更多还原
