【摘要】 分析了海水蒸发器的工作流程,构建了海水蒸发器水位的数学模型。针对海水蒸发器水位存在的延迟环节,提出了预估补偿控制与PI控制相结合的控制方案。仿真结果表明,采用带预估补偿器的PI控制,能使海水蒸发器水位控制系统的调节品质和稳定性得到改善。更多还原

【Abstract】 The process of seawater evaporation plant is analysed in this paper,then the mathematical model of the water level of seawater evaporation plant is established.A new control scheme that combines predictor control with PI control is put forward to resolve the time-delay of seawater evaporation plant.The simulation result is given to prove that the quality and stability of the water level control system is improved afer the PI control with predictor control is adopted.更多还原
