Large-scale systems
The theory of control applied to Large-scale systems presents new challenges due to the extense size of the plants and to iis structure. The goal to be achieved with the control methods applied to this kind of systems, is to obtain solutions with a reasonable effort in modelling, designing and implementation of the controller.
These systems are characterized by having a great number of components that work in a coordinated way (most of them in a remote way), many times distributed along a large surface, and in which the resources are limited. Apart from guaranteeing that each component of the process is properly working, according to some pre-defined conditions, the objective of control of these systems requires to planify an strategy of operation, so that depending on the available resources, it will be possible to fulfill concrete demands.
This is for example the case of the water distribution systems or the water resources of a basin.
To give solution to these problems, the research group has two lines of work in this area:

To give solution to these problems, the research group has two lines of work in this area:
- Strategies for the validation of data coming from the networks of sensors
- Planning employing techniques of Predictive Control based in models (MPC)
- Application of these techniques in a centralized and decentralized way
The CER CS2AC-UPC group has been working on several projects where the mentioned MPC control has been applied, in particular in the area of water:
- PLIO/SOSTAQUA/WIDE: Application to the networks of potable water
- CORAL/OPTIMAR: Application to networks of sewerage
- GERHYCO/PREDO/HIDROPTIM: Application to irrigation systems
As a result of these projects several tools of software have been developed, allowing to implement the MPC control in real-time.
