i-Sense main objective

The main objective of this project is to develop intelligent data processing methods for analyzing and interpreting the data such that faults are detected (and whereas possible anticipated), isolated and identified as soon as possible, and accommodated for in future decisions or actuator actions. The problem becomes more challenging when these sensing/actuation systems are used in a wide range of environments which are not known a priori and, as a result, it is unrealistic to assume the existence of an accurate model for the behavior of various components in the monitored environment. Therefore, this project will focus on cognitive system approaches that can learn characteristics or system dynamics of the monitored environment and adapt their behavior and predict missing or inconsistent data to achieve fault tolerant monitoring and control.

i-Sense SAC

In the framework of the iSense project, SAC group works on the implementation of Fault Diagnosis and Fault Tolerant Control (passive, active, model predictive) strategies in different applications suggested by the different partners involved, as for example, Water Distribution Networks, Robotic Systems and Intelligent Buildings. In case of Water Networks, the case study used in the project is the Barcelona Transport Network (which supplies water to approximately three million consumers, distributed in 23 municipalities in a 424 m2 area) among others (e.g. Environmental Monitoring, Smart Buildings, Robotic Applications). A model of the Barcelona water network which may simulate certain types of faults that may occur in different elements of this network (e.g. actuators, sensors) is also developed by SAC group, in order to use it as a benchmark by all the partners involved in the project. Furthermore, data validation and reconstruction strategies are also developed, in order to be applied in the applications presented.
