In the case of one phase failure, the switched reluctance motor (SRM) will behave nearly the same, both in open circuit and in short circuit failure. This means, that the machine will understand the two faults in the same way which makes the SRM faults detection and diagnosis a more challenging task. In this paper, a diagnosis method based on statistical pattern recognition (PR) analysis associ...

this paper presents the hardware simulation (based on vhdl code) of a multiple-fault tolerant cellular genetic algorithm. this study aims to increase the immunity of cellular genetic algorithm in multiple-fault situation. here, multiple-fault refers to the situation that seu (single event upset) occurs simultaneously at two or more bits of the chromosome and fitness registers. the fault model i...

the khushab anticline is located in the zagros fold-thrust belt in the lurestan. this anticline is affected by the balarud fault zone, which is a part of mountain front fault between the lurestan and dezful embayment zones. based on the measurement of the elements of fold style, this anticline is analyzed. according to these measurements, this anticline is a noncylindrical, asymmetrical and dis...

Equivalent faults inhibit fault diagnosis by producing indistinguishable test metric measurements. Removal of conditions causing the equivalence in response exhibited by such faults is necessary if fault diagnosis quality is to be improved. As Design-for-Testability methodology aims to deliver a degree of fault diagnosis substantially greater than that obtainable testing unassisted by on-chip t...

Multiphase machines are very convenient for applications that require high reliability. In this two-part survey, the state of art about fault tolerance in multiphase drives is reviewed. Part 1, an overview including numerous types was presented, along with fundamental notions drives. Here, 2, focus placed on phase/switch open-circuit (OC) faults particular, which have received most attention li...

Delay faults are an increasingly important test challenge. Traditional open and bridge fault models are incomplete because only the functional fault or a subset of delay fault are modeled. In this paper, we propose a circuit level model for resistive open and bridge faults. All possible fault behaviors are illustrated and a general resistive bridge delay calculation method is proposed. The new ...
