Rolling element bearing defects are among the main reasons for the breakdown of electrical machines, and therefore, early diagnosis of these is necessary to avoid more catastrophic failure consequences. This paper presents a novel approach for identifying rolling element bearing defects in brushless DC motors under non-stationary operating conditions. Stator current and lateral vibration measurements...
This paper implements an interval Kalman filter (IKF) for the navigation of the Springer uninhabited surface vehicle. Interval filters become necessary when the system dynamics are not known precisely or vary unpredictably, but can nevertheless be described in terms of bounded intervals. Such filters based on interval systems require the use of interval arithmetic (IA) for their operation. One of...
