Fault diagnosis of actuators in flight control system of an unmanned tandem helicopter has been studied in this paper. A support vector machine (SVM) observer is designed to parameter estimation and model compensation for its uncertainty, and then to fault detection. Further more, a fuzzy sample SVM (FS-SVM) based diagnostic tool is used to fault diagnosis for the actuators of the small tandem helicopter,...
A practical fusion algorithm for tracking maneuvering target based on centralized structure of multi-sensor is proposed. This algorithm is implemented with two filters and state fusion, together with the current statistic model and adaptive filtering. Firstly, the fusion weighting coefficients are obtained using the stochastic approximation theory, a suitable method of estimation measurements noise...
