Summary:In this paper, fault detection and diagnosis of a permanent-magnet
DC motor is discussed. Parameter estimation based on block-pulse
function series is used to estimate the continuous-time model of the
motor. The electromechanical parameters of the motor can be obtained
from the estimated model parameters. The relative changes of
electromechanical parameters are used to detect motor faults. A
multilayer perceptron neural network is used to isolate faults based on
the patterns of parameter changes. Experiments with a real motor
validate the feasibility of the combined use of parameter estimation and
neural network classification for fault detection and isolation of the
motor
