摘要
针对采用活性污泥法的污水处理系统,研究其鲁棒保成本控制问题。根据活性污泥法污水处理过程的特点,建立范数有界的不确定系统模型;利用Lyapunov稳定性理论和线性矩阵不等式方法,设计鲁棒保成本状态反馈控制律,使得闭环系统鲁棒渐近稳定,并且系统的性能指标不超过某个确定的上界。以某污水处理厂的污水处理系统为例,应用所设计的控制器进行仿真研究,结果表明:所设计控制算法是有效的。
Aiming at wastewater treatment system using activated sludge method,the problem of robust cost control is studied.Firstly,according to the characteristics of activated sludge wastewater treatment process,a norm-bounded uncertain system model is established.Then,using Lyapunov stability theory and linear matrix inequality method,the robust guaranteed cost state feedback control law is designed to make the closed-loop system robust asymptotically stable,and the performance index of the system does not exceed a certain upper bound.Finally,taking the wastewater treatment system of a sewage treatment plant as an example,the designed controller is applied for simulation research.The results show that the designed control algorithm is effective.
