摘　　要：针对城市污水脱氮过程中的非线性时变特性与强扰动问题,提出一种自适应模糊滑模控制策略。首先,结合模糊控制和滑模控制方法,建立了适用于城市污水脱氮过程的自适应鲁棒控制结构;其次,基于滑模面对系统的动态影响,设计了控制参数实时调整方法;最后,依据李雅普诺夫理论,证明了控制系统的稳定性。基于国际基准仿真平台的实验结果,验证了所述方法的有效性。所述方法可以自适应调节参数以适应工作环境的变化,从而能在环境复杂变化的城市污水脱氮过程中改善控制性能,保障系统长期可靠运行。To address the challenges of the time-varying nonlinear characteristics and disturbances in municipal wastewater denitrification process,an adaptive fuzzy sliding mode control strategy is developed.First,an adaptive robust control framework is established based on fuzzy control and sliding mode control method.Next,based on the dynamic response of the sliding surface on the system,a real-time adaption law of the control parameters is designed.Finally,the stability of the system is analyzed and proved by the Lyapunov stability theory.The effectiveness of the proposed method is demonstrated by the test result on benchmark simulation platform.The proposed method can improve the control performance and enhance the long-term reliability for municipal wastewater denitrification process by the control parameters adapting to changes in the time-varying operation environment.
