摘要
针对污水处理中的不确定参数和不稳定问题,采用改进的内模控制,对变参数活性污泥法污水处理系统的溶解氧浓度进行控制,并对控制器参数进行优化。仿真结果表明:该方法可以快速逼近溶解氧的给定值,并具有较强的抗扰性和鲁棒性。
Considering the uncertain parameters and unstable problems in wastewater treatment,an improved internal model control-partial internal model control（PIMC） was proposed to control DO concentration in the activated sludge model with varied parameters and to optimize the parameters of the controller.The simulation results show that PIMC can track the set value of DO fast and the method has great anti-disturbance and robustness.
