    Keywords : Reliability; Maintenance; CBM; Health prognostics;

    Abstract : Industry 4.0 push forward the development of concepts such as artificial intelligence, big data, and Industrial Internet of Things, which claims an evolution of the monitoring systems design in terms of the accessibility to the information. READ MORE

  6. 5. Diagnostics and Prognostics of safety critical systems using machine learning, time and frequency domain analysis

    University essay from Blekinge Tekniska Högskola/Institutionen för tillämpad signalbehandling

    Author : Pratik Purkayastha; [2019]
    Keywords : Diagnostics; Prognostics; PHM; predictive maintenance;

    Abstract : The prime focus of this thesis was to develop a robust Prognostic and Diagnostic Health Management module (PDHM), capable of detecting faults, classifying faults, fault progression tracking and estimating time to failure. Priority was to obtain as much accuracy as possible with the bare minimum amount of sensors as possible. READ MORE
