This paper proposes a new method for Astronautically Phased Mission System (APMS) reliability assessment based on Multi-source data fusion. Traditional methods for APMS reliability assessment have two problems. One is lack of overall consideration of the different product hierarchies, different development stages, and different stress conditions data. The other is too difficult to give the reliability...
Multispectral true color image products of satellites are widely used. Whereas, the images straightly synthesized by the three bands of multispectral data are usually dark and get heavy chromatic aberration, which are not available. Therefore, a brief and efficient method of processing multispectral true color images is needed. A way to solve this problem is proposed in this paper. It combines the...
Aiming at the characteristic that small satellite storage battery usually has no enough ground experiment & in-orbit telemetry data, a new Dynamic Bi-step MPNN based method is proposed to solve the problem of life prediction of small satellite storage battery. The method can mainly be divided into two steps: The first named 1st-MPNN process is to establish a modified probability neural network...
Fuzzy temporal association rules can take into account the temporal requirements of the user which tend to be ill-defined or uncertain. However, fuzzy temporal association rules still have some shortcomings: firstly, neglecting the effect of all kinds of potential negative examples that affect its expression capability; secondly, probably showing no practical significance or even misleading even if...
Notice of Violation of IEEE Publication Principles"Sensor Fault Reconstruction for Satellite Gyroscope Using Eigenstructure Assignment,"by Luan Jia-hui, Tao Lai Fa, Lu Chen,in the Proceedings of the WRI Global Congress on Intelligent Systems, 2009 (GCIS '09), vol.2, May 2009, pp. 318-322After careful and considered review of the content and authorship of this paper by a duly constituted...
For the momentum wheel control system of satellite, a method to design sliding mode observers for reconstructing actuator fault is presented. It uses the equivalent output injection concept to explicitly reconstruct fault signals, and uses concept to design the sliding motion so that the effect of the uncertainty on the reconstruction of the faults will be minimized. This method can estimate the existing...
