This paper, the last part of our three-part contribution, is concerned with the diagnosis of faults in the discrete-time hybrid system model, described in Part I. The original contributions of the paper are as follows. Fault have been modeled in terms of activity states labelled as faulty. The problem of diagnosis is formulated based on that of state estimation, as described in Part II. The timed sequence of the estimates of the current state of the overall system from the Observer is then used for fault diagnosis.
