Abstract
A computer-implemented method for automatically identifying a faulty behavior of a control system. The method includes receiving, at a test processor, a description of the faulty behavior. The method also includes selecting, using the test processor, a goal state based on a heuristic decision. The method also includes selecting, using the test processor, a selected system state. The method also includes selecting, using the test processor, a selected variable to the control system based on the goal state. The method also includes loading, from a memory, a control model of the control system. The method also includes performing, using the test processor, a simulation of the control model using the selected variable and the selected system state as parameters of the simulation. The method also includes determining, using the test processor, whether the faulty behavior was observed based on the simulation.
