摘要
通过对自来水净水过程中存在的浊度PH值等因素变化的滞后性、扰动性以及系统动态的复杂性等问题的分析,为了提高净水质量,确保净化后的水质达到国家标准,找出了自来水净水过程的基本控制关联,建立由浊度和PH值两条主要因果链组成的相互关联的结构分散化控制模型。根据模型设计了链预估计算法和链式系统控制算法。进行了系统仿真,仿真结果表明该系统具有良好的稳定性以及抗干扰能力。
Through analyzing the water purification process which consists of factors such as changes in turbidity, PH value of the lag, disturbance, and system dynamic of complex issues, in order to improve water quality and ensure purified water up to the national standards, the basic control correlations in the process of water purification are found, established by the turbidity and the PH value of the two main causal chain structure consisting of interconnected decentralized control model. According to the model this paper designs the chain pre- estimation algorithm and chain system control algorithm. It makes system simulated. Simulation results show that the system has good stability and anti-jamming capability.
