Predicative Control in the Water Transfer Canal for Sluice at Constant Water Levels Maintenance
An improved predicative control model was derived from on-line system identification to solve the optimization of water transfer processes. Using linearized storage volume regulatory model of the open-channel flow, canal operation problem was formulated as an optimal control problem to regulate sluice discharge with water level error as its constraints, in which time delay for water level tracking flow variation was fully considered. a dynamic parameter adjustment mechanism was developed based on prior physical information to improve the model accuracy. System stability was guaranteed using H∞ robust control strategy in the close loop for constant level control of an in-line canal. The response of pools to downstream withdrawal was examined in terms of their sluggish recovery even when the correct flow change is applied upstream. These results show the method enables to combine both classical politics, keeping the distant downstreaM control water management while recovering the local upstream control real-time performance with respect to the user.
