Abstract:

This paper investigates the problem of imbalance fault estimation for rotating machines. To enhance reliability, in addition to vibration responses, a mathematical model of rotating machinery dynamics is developed for condition monitoring purpose. An unknown-input observer design method is further proposed for imbalance fault estimation. Validation of the proposed design method is performed by simulating an idealized rotating machine Simulink model, which is composed of SimMechanics blocks and custom finite-element-model (FEM) based subsystems. The potentiality of the proposed methodology and the feasibility of constructing the rotor system in SimMechanics are also investigated in this paper.
