| 摘 要： | 针对活性污泥污水处理系统的机理模型具有复杂的非线性,传统的控制方法存在着精度不高,自适应能力差等缺点,提出一种优化的自适应模糊神经网络控制方法,分析了控制模型参数对系统的影响,并经过数据训练得到控制器各参数的寻优方法,获得系统的最优化参数。该控制方法能够快速、有效地使曝气池中溶解氧浓度达到期望值,并且具有较高的控制效果与控制精度。与传统控制方法相比,该控制方法更具有鲁棒性。仿真结果验证了该控制方法的有效性和正确性。

| Abstract: | According to the complex non-linear mechanism model of activated sludge sewage treatment system and the shortcomings of low-precision and poor adaptive capacity of traditional methods of control, a fuzzy optimization of the adaptive neural network control method was given. The influence of control model parametersto the system was ana- lyzed. The controller parameters optimization methods were obtained by data trained and the optimized parameters of system were gotten. The control method had good effect and high precision, and could quickly and effectively make the concentration of dissolved oxygen aeration tank meet the expectation value. Compared with traditional control method, this control method had more robustness. The simulation results show the effectiveness and correctness of the control method. |
