Título: An Introduction to fault Diagnosis Systems with Application to Aircraft Turbine Engines and Wind Turbines”
Resumo:
Fault diagnosis systems, also called condition monitoring systems, provide on-line information on the state of health of a device or a process. They aim at detecting small degradations, so that maintenance operations can be planned in due time, before the faults lead to process shut down. In this seminar, the typical structure of a fault diagnosis system will be introduced. It is made of two parts: a residual generator and a decision system. The first aims at generating fault indicators (also called residuals) from the measurement recorded on-line. The second processes the residual signals in order to provide a list of the most likely fault(s), if any. Next the principle of a design method for both parts will be presented. The methodology will then be illustrated on two applications, namely leak detection in the lubrication system of an aircraft turbine engine, and sensor monitoring in wind driven doubly fed induction generators.
