摘　　要：针对丢包引起网络控制系统性能下降问题,以广地域分布的城市污水排放系统监控网络为对象,给出泵站对象数学模型,继而在建立基于异步动态系统的监控网络丢包切换开关模型的基础上,提出了一种丢包智能补偿策略,经Truetime平台仿真和区域泵站实际运行控制试验。结果表明,该丢包补偿策略能有效提高污水排放监控网络系统的控制性能。Aiming at the performance degradation of network control system caused by packet-loss,taking the urban sewage disposal system monitoring network with wide geographical distribution as study object,based on giving a mathematical model of pump station and subsequently establishing a switch model of monitoring network packet-loss according to the asynchronous dynamical system,this paper puts forward a network packet-loss intelligent compensation strategy. Then the compensation strategy is simulated by the Truetime platform,and some experiments on the operational control of local pumping stations are done.The results show that the compensation strategy is effective to enhance the control performance of the sewage disposal monitoring network system.
