Abstract :
In this work a hybrid technique that includes probabilistic and optimization based methods is presented. The method is applied, both in simulation and by means of real-time experiments, to the heating unit of a heating, ventilation air conditioning (HVAC) system. It is shown that the addition of the probabilistic approach improves the fault diagnosis accuracy.
