FAULT DETECTION IN A DC MOTOR USING THE ADAPTIVE THRESHOLD LMS (ATLMS) TECHNIQUE

Abstract

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 dierent 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 xed for the rest of the simulation no matter how the input signal changes; and fault 3 presents an exceeding
RPM value.
