Parts For Aircraft Engine Mbc Control Performance Tracking Filter Study

Tracking Filter is a important component of MBC(Model-Based Control) system. In this paper, A aero-engine performance tracking filter is designed by Kalman Filter algorithm. The filter estimate the ECDP(Engine Component Deviation Parameters )which reflect the deterioration of engine and the variation between engines. The estimate parameters are used to tune the embedded model to make the model consistent with the engine which respect. Then the model is used to calculate the engine performance parameter. The change of ECDP is modeled in a state-space perturbation formulation. Author reformulate the mathematic model of engine to process the ECDP as the state parameters of model, expatiate on the prove of the filter stability, study the filter volatilization phenomenon by freezing K matrix and compensating the model by ECDP. The volatilization of filter is solved in simulation environment. Four tracking filters are designed by altering the component of observe parameter to detect the effect of different component. All four filters are evaluated in different position of fly envelop.
