Matrix method for diagnosing functional failures and stuck-at faults in software or hardware units is proposed. It is based on qubit or multi-valued data structures for defining diagnostic information, which allows significantly reducing the computational complexity of the simulation and diagnosis due to the introduction of parallel logical operations on the matrix data.
The paper is indented for detection and diagnosis of three-phase bridge rectifier faults. The diagnosis is desirable in order to ensure product quality and improved operational efficiency of rectifiers as the mains power supply. The currents of three phase bridge rectifier are analyzed in order to achieve information for the detection of faults. We observe current and output voltage differences between...
Induction motors are critical components in many industrial processes. Therefore online monitoring of induction motors is becoming increasingly important. The main difficulty in this task is the lack of an accurate analytical model to describe a faulty motor having different types of faults like winding faults. To model shorted stator turns, the model assumes that the one of the phase has two windings...
