Towards a MPC for open water systems considering both quantitative and qualitative aspects
| Resumo: | Model predictive control (MPC) is a well known technique for hydraulic structures control in open water systems. Many examples of its application are implemented considering quantitative aspects, like water levels in reservoir and canals or discharges at turbines or pumps. Our aim is to develop and implement a model predictive controller for hydraulic structures of reservoirs considering water quality aspects of canals, rivers or reservoirs. An example, based on a drainage system of a polder composed by several connected canals will be presented. We use model predictive control in order to control the level of water in the polder canals. In this problem, some restrictions should be taken into account. More concretely, the water level should not exceed a certain maximum value, it should not be lower than a certain minimum value, and the capacity of the pump ow is limited. We simulate the water level controller performance for several scenarios, and weather conditions, and we compare the results with other control techniques. The rational to further implement qualitative aspects will be presented. |
