... availability. The gas leakage is detected without downtime by using a model- based approach together with a bank and extended Kalman fil- ters (EKF s). The residual is analyzed using multi-model adap- tive estimation (MMAE). The applied accumulator model relies on a thermal time constant describing the heat...

... Unforeseen failures of hydraulic power generation systems can cause costly operation interruptions of aircraft. To overcome this, a health monitoring of the system components is desirable but not yet available. In this paper, a method is presented that allows a model-based development...
