Based on the mathematical model of variable geometry turboshaft engine parts, which reflects the health status of components, a linear state-space mathematical model reflecting the health status of aero-engine is established by using the linearization method. Using the Kalman filter theory, filter. The linear state space model and the state of health tracking filter are simulated. The results show that the linear state mathematical model is accurate and real-time. The state-of-health tracking filter can accurately estimate the change of the health state of the turboshaft engine.
