The real time and continuity flight safety monitoring based on ADS-B raised to solve the ACARS report sparse uneven and time *** structure of real time flight safety monitoring based on ADS-B is proposed firstly, which monitor the human factors during flight. Then in the concept of practicality and reliablity, an integrative simulate platform for flight safety monitoring is established with current cyber-assistant software. Based on real time flight safety monitoring architecture and simulate platform, the normative flow for the design of flight safety monitoring is set up.

Considering nonlinear behaviors and environmental disturbance of the boiler pressure control system, a linear interpolation fuzzy controller is developed. First, according to the conventional discrete fuzzy control principle, a discrete fuzzy controller for the system is designed and a 2-D fuzzy control lookup table is deduced. Then, to overcome the conventional fuzzy controller's disadvantage of lower precision caused by discretization, a bilinear interpolation 2-D table lookup method is used to replace the exact lookup method, with which continuous output can be obtained from the discrete control table. Finally, based on the existed computer control system and boiler system hardware configuration, hard-in-loop real-time simulation system is established in Matlab/RTWT. Lots of experiments are carried out. And the results prove that better control performance can be achieved with the proposed control scheme.

With the development of the infrared imaging guiding missile, more and more simulations are required. These simulations often include: the close-loopsimulation, the open-loop testing, the performance evaluation of the anti-interference and etc. In order to carry out these simulations, infrared images which include targets, backgrounds and interference are required. A hard-in-loop simulation was presented to generate these dynamic images. The infrared image, as the signal resource of the guider, is composed of four models: target, background, interference and atmosphere. The infrared radiation characteristic of the target, background and interference is the direct factor which influences the infrared images. And the existence of the atmosphere brings on the radiant attenuation. The targets and interference are combined into the backgrounds by the technology of computer image generating (CIG). Two types of schemes of the hard-in-loop simulation are given: open-loop and close-loop. This can achieve the arbitrary changing of the battlefield, accordingly, the battlefield adaptability of the infrared imaging guiding weapons can be assessed in laboratory. It is no other than an important performance that is difficult or not to be assessed in outfield experiments.
