An Adaptive Statistical Approach To Flutter Detection
نویسندگان
چکیده
Flutter is a critical instability phenomenon for aircrafts. In previous investigations, the authors have proposed several online statistical subspace-based algorithms for flutter monitoring. Each algorithm monitors some stability criterion (damping, flutter margin...) w.r.t. a fixed reference flight point using the online Cusum test. The drawback of this technique is that the flutter detection corresponds to a light trend of the criterion toward instability and thus the estimated flutter airspeed is conservative. In this paper, a new moving reference version is proposed which intends to give a better estimation of the flutter airspeed. Application on simulation data shows the relevance of the new algorithm.

Most of the inventory control models assume that quality defect never happens, which means production process is perfect. However, in real manufacturing processes, the production process starts its operation in the in-control state; but after a period of time, shifts to the out-of-control state because of occurrence of some disturbances. In this paper, in order to approach the model to real man...
