Method for estimation of at least one engine parameter

摘要: A system comprising determination of tuning parameters enabling optimal estimation unmeasured engine outputs, e.g., thrust. The level degradation performance is generally described by unmeasurable health related to each major component. Accurate thrust reconstruction depends upon knowledge these parameters, but there are usually too few sensors estimate their values. set determined which accounts for representing the overall effect larger as closely possible in a least squares sense. method utilizes singular value decomposition matrix generate parameter vector low enough dimension that it can be estimated Kalman filter. Generation specifically takes into account variables interest. facilitate matching both measured and well state variables.
