Abstract:China is currently working on the construction of the massive South-North Water Transfer Project (SNWTP), the largest project of its kind ever undertaken. Planned to be completed ultimately by 2050, over 300 million people are expected to benefit from the transfer of 44.8 billion m3 of water per year. The project corresponds to China's severe water scarcity and geographically uneven south-north distribution of water. The Jiangsu water transfer system is a 411 kilometers long section of this project and will divert as much as 8.9 billion m3=year (up to 500 m3=s ) from the lower Yangtze River reach uphill through an existing network of canals and lakes of Jiangsu province in the direction of the Yellow River and Beijing. The water system serves many functions such as drainage, flood control, navigation, water supply and from 2013 the new function of water transfer to the north is added. In order to fulfill these functions, controllable structures, such as gates, weirs and pump stations are used. The daily operation of these structures is referred to as real-time control and is subject of this thesis. Real-time control of a complex water system as the Jiangsu water transfer system with different (sometimes conflicting) objectives preferably requires advanced control techniques in order to meet the desired system behavior. Model Predictive Control (MPC) is such an advanced controller that has shown good performance on a number of different water systems (Overloop [2005]). MPC is a control algorithm that makes explicit use of a simplified process model (internal model) of the real system to obtain control actions by minimizing an objective function over a prediction horizon. It has been suggested by Dutch experts that the Jiangsu water transfer system may be controlled by the advanced Model Predictive Controller. This might contribute to meet the desired system behavior and increase the water system's performance. This hypothesis is tested in this thesis by studying an idealized reflection (schematization) of the Jiangsu system.
