摘要：a system for controlling gas turbine engines in real time includes a digitalprocessor (52) which uses a set of scalar coefficients and the current value of variousparameters of operation(engine to predict the current value of a set of engine

performance parameters.the actual values of these parameters are controlled, and theperformance compared with the values predites (56) for sending signals to a logic errordeviation of control (62).an indication of the error in the rnit detectors which provide theactual values of controlled parameters and performance in the gas turbine engine (10).inaddition,the deviation signals are used in the digital processor unit (52) to determine anestimate of a time dependent root mean square (rms) of each parameter controlleadingrole. the root mean square estimation signals are sent from a logical pattern (72) thatprovides prognostic information.in order to adapt the control system to a particularengine control engine.the system can operate in a mode or a digital filtering calibration isused to determine automatically the values of the coefficients that reflect thedifferences of the normalance between the engine control and other engines of thesame type.given that a similar digital filtering is used to determine the characteristics oftemporal parameters of the engine, and a control processing structure for a digital

processor)a are used for the calibration of the system, and the estimation of theparameters or characteristics of trends over time.
