Controller reconfiguration based on a qualitative model: A solution of three-tanks benchmark problem

In this paper a reconfiguration method based on a qualitative model of system is described. This method is useful whenever the obtained data from system is in qualitative form. By searching the graph representing the qualitative model of the system, an algorithm is given such that the qualitative states of the system can be transferred to desired qualitative states considering different faulty-cases. For more illustration, a solution of the Three-Tanks Benchmark problem is given using the presented method.
