A baseline expert control system for marine gas turbine compressor surge

United States Navy gas turbine ships are in need of casualty control system updating to reduce demanding conditions on engineering watch standers, to increase equipment longevity, and reduce operating costs. This thesis presents a baseline computer-based expert system controller concept developed for the critical casualty control problem of gas turbine compressor surge. The controller design rests on the building-block components of real-time gas turbine simulation and compressor surge characterization, which is discussed. The logic and rules for the expert system design are presented, as is a dynamic investigation of the expert system diagnostic performance. http://archive.org/details/abaselineexpertc1094526900 Lieutenant, United States Navy Approved for public release; distribution is unlimited.
