This paper describes the use of artificial intelligence-based techniques for detecting and isolating sensor failures in a turbojet engine. Specifically, three artificial intelligence (AI) techniques are employed: artificial neural networks (NNs), statistical expectations, and Bayesian belief networks (BBNs). These techniques are combined into an overall system that is capable of distinguishing between...
The use of soft computing algorithms in hardware-in-the-loop applications has been investigated. A fuzzy logic controller (FLC) was designed and successfully tested on the Turbine Technologies SR-30 turbojet engine for the main-stage operation of the engine. A transfer function model of the plant was obtained using frequency-response methods. To ensure safe operation of the engine, a PID controller...
