..., is also presented, along with design steps for adjusting the dynamic response of the Kalman filter state estimates. Results from the application of the technique to linear and nonlinear aircraft engine simulations are presented and compared to the conventional approach of tuner selection. The new...

... hydrodynamics motion measurement state estimation machine theory rotors Turbogenerators used for power generation consist of several rotor stages that are rigidly coupled together to form a single rotor supported on many hydrodynamic bearings, resulting in a statically indeterminate rotor-bearing...

... experience and previously published data 17 and are shown earlier in this paper. The Kalman filter was relinearized around the state estimates every 50 flights. We used a 1σ process noise in the Kalman filter equal to approximately 1% of the nominal state values to allow the filter to be responsive...

... state estimation machine bearings Over the past 30 years, theoretical models have played an increasing role in the rapid resolution of problems in rotating machinery. Adams and McLosky 1 give a description of some early applications while further examples are given in 2 . A variety...
