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.
This paper proposes an innovative fault diagnosis system for a turbocharged diesel engine with variable geometry turbocharger control. Numerous and diversified actuator faults are identified and analyzed such as air leakage in the admission collector, compressor malfunctioning, intake valves fault, intercooler fault, deterioration in the turbine-compressor coupling, defect in the variable geometry...
