Resumo

Any engineering application is susceptible to fault occurrence which can cause a major damage on processes. This paper discusses the application of detection fault theory on DC motor using the ATLMS, and adaptive threshold technique, with structured residual generation. Here, three different faults were studied and evaluated with regard to fault detection promptness on the proposed system. Fault 1 results in RPM deviation from normal to zero value; fault 2 describes a situation where the RPM value at the time of fault occurrence is kept fixed for the rest of the simulation no matter how the input signal changes; and fault 3 presents an exceeding RPM value.
