As for the low forecasting precision problem about time series in avionics complex system, a time series combined forecasting model of complex systems was established based on GM (grey model is referred to as GM). However, complex system failure prediction by conventional GM(1,1) model may yield large forecasting errors. In order to overcome disadvantage of the conventional GM(1,1) model, this paper derived the traditional GM(1,1) model (abbreviated as DGM(1,1)), which can predict more accurately on non-geometric sequences. Combining DGM(1,1) with particle-swarm optimization algorithm, a kind of PS-DGM (1,1) forecast model was established to minimize such errors. Forecasting sequence was calculated by means of DGM(1,1) model, then particle-swarm optimization algorithm was used to modify them further, and the degradation trend prediction of characteristic parameters of avionics complex system was realized. The experimental results indicate that the validity of PS-DGM(1,1) model was testified by tracking and forecasting the experiment data of avionics equipment in real environment, and higher precision is gained by the proposed model than traditional one. © 2018, American Institute of Aeronautics and Astronautics Inc, AIAA.

In this paper, a new guidance law based on SDRE method is designed to solve the problem of terminal angle constraint of a missile by using nonlinear kinematics model and dynamic model of a missile. The constraint of collision angle can be realized by the guidance law under the condition of satisfying the requirement of miss distance of terminal guidance. In addition, the guidance instructions in the form of feedback and the analytic solution of the guidance law are obtained in the two-dimensional plane. Compared with previous terminal guidance methods, the advantage of the method is that it does not depend on the estimation of the time to go. The effectiveness of the proposed guidance law can be verified by digital simulation.

airborne integrated electromechanical management system (IEMS) is a safety critical system, ensuring the aircraft normal flight and the normal operation of each function of the plane. This paper analyses IEMS of the current fighter aircraft, EAP, F-22 and F-35, proposes an architecture modeling and simulation method of IEMS. This method establishes a common model of IEMS, forms modeling and simulation process of IEMS, detailed designs monitoring and redundancy management algorithms based Simulink. Finally, we have applied the methodology on a commercial aircraft and verify the feasibility, accuracy and effectiveness of the modeling method.

Future avionics is no longer mere close electronic systems with the requirement changed, while it is pervasively controlled by dozens of frequent information exchange, open architecture and highly automatic systems. And this transformation has driven major advancements of security in avionics which contains computing security and communication security. Our team is focused on the security of next generation avionics, including security requirement, standard, architecture, topology, procedure and so on. Then we carried out the preliminary research on the secure integrated computing. The ultimate goal is to provide more security while containing costs and restraining the growth of Size, Weight, and Power (SWaP) to future avionics equipment.

To achieve better performance for multi-channel and multi-chip SSD, the DAT scheme exploits light-traffic periods and multi-level parallelism inside SSD to write some buffered dirty data back to flash proactively. However, the appearance of large request will cause extra flash write operations. In this paper, a novel write buffer scheduling algorithm H-DAT is proposed based on former DAT, the identification of large request allows H-DAT to service large request and small request separately so that H-DAT can achieve better performance without loss of endurance. The results of our extensive trace-driven simulation show that H-DAT performs DAT in both performance and endurance.
