For the problem that the airdrop of inner equipment coupled with the crosswind affects the flight safety and completion of the airdrop mission, a novel controller based on the L1 adaptive control was designed. State feedback control signals were produced by the optimal control and the matched reference model was determined. On this basis, we transformed the system nonlinearity into the matched and...
In this paper, a noise reduction approach for hyperspectral images (HSIs) is presented. Due to the assorted noise sources of HSIs, it seems difficult to describe the noise in a concise manner. Commonly, noise reduction algorithms are dedicated to a certain kind of noise, such as random or striping noise. Most of them in addition have somewhat idealized hypotheses. For example, the random noise is...
A distributed hydrological model that can simulate the hydrological processes of watershed by considering both saturation-excess and infiltration-excess runoff mechanisms is intruduced. The model is based on MapWinGIS platform and adopts modular programming ideas, watershed features such as river network and subbasins can be extracted automatically. In the model, the hydrological processes of watershed...
As the loss probability could be the indicator of congestion possibility, the theoretical study of air traffic network was how to determinate active queue management (AQM) based on random condition. Then, a random early detection (RED) method for air traffic network was proposed, which determined the soft loss strategy with deducing the maximum threshold and average queue length. Compared to the existing...
