Abstract
The objective of the FAPEPS thematic project entitled Fault Tolerant Identification and Control of Rotating Systems (grant #2015/20363-6), as the name suggests, is the development of a system capable of identifying faults in a rotating system in order to control or compensate them. This control, or compensation, must allow the faulty machine to remain operational in its design condition until the next scheduled maintenance, or to be safely shut down, in the case of a severe fault with the need of an emergency maintenance. In this sense, such system can be divided into four steps. First, a vast acquisition of information through the sensors is realized and all the collected data is filtered and processed. Next, it is realized the search for faults in the machine from the processed signals. If any fault is detected, the third step consists in identify the fault type, its location, and severity degree. Finally, a magnetic bearing is used to compensate the effect of the fault and allow the machine continue a safe operation. Initial results of the research, comprising the first three steps described, were published in international journals and conferences. (AU)
