| 摘 要： | 针对某污水处理示范工程,对于一体化氧化沟的转刷曝气控制系统及相应的控制算法系统进行了研究.设计了全数字化的闭环控制系统,以溶解氧指标为控制对象进行了控制算法设计,针对转刷曝气工艺的特点,采用神经PID调节算法,引入了线性神经元(NNC)对经典PID算法进行优化、应用梯度下降法对NNC网络权值进行在线计算.在实验的基础上,确定了网络权值的初始值.采用C语言实现了算法的编程,该控制系统已在示范工程中得到初步使用.

| Abstract: | The rotor aeration control system and control algorithm are studied based on one model sewage treatment plant. The digital closed-loop control system is designed and the dissolutive oxygen (DO) control algorithm is given out using neural PID algorithm. The traditional PID algorithm is optimized by neural network cell (NNC) method and the weight value of NNC is generated on-line. According to experimental results, the initial weight value of NNC is determined. The algorithm is realized by C language. |
