Abstract

In this paper a special measurement system suitable for on-line fault diagnosis on dynamic systems is presented. The proposed system, employing an array of processors, is interfaced with the process by means of a special data acquisition unit. Due to its high throughput, it can be successfully used in many industrial plants and devices, including those requiring very short diagnosis times such as electrical drives. Fault detection and localization are obtained by adopting a model-based method using a bank of fault detection filters. First results regarding the diagnosis of an induction motor are presented, and the main problems encountered with such an application are analyzed and discussed
