Controlling Urban Drainage Systems
The key issue in urban drainage (UD) systems, looking from a control engineering perspective, is operation. Measurements, feedback, control and automation are tools to address the challenges. Measurement technology combined with analysis and parameter estimation are used to obtain relevant information for decision and control. The UD control problem is truly multivariable with many sensors and actuators. A major concern is how to define performance indices that reflect requirements from the natural and urban environment and how to translate this into operational variables. This makes the UD system operation a multi-objective control problem
