Journal of System Simulation
Abstract: Through the secondary development of Google Earth, flight training simulation system for visualization of realization, the system used B/S structure, the client browser using Google Earth, all the development on the server side. Mathematical model of aircraft was constructed; 3D modeling software SketchUp was used to establish a realistic fighter jets, missiles, high and low speed flame and other 3D model; the established 3D models was imported into Google Earth; by Microsoft VC ++ 6.0, the secondary development on Digital Earth was achieved, and the control of aircraft and other 3D models was realized; Matlab was used to verify …

Research On Control Technology Of Aeroengine Heat Exchanger, Qingyang Jiang, Song Hua
Journal of System Simulation
Abstract: In order to solve the high temperature problem caused by the high speed of the synergistic aspirating engine, this paper designs a control algorithm for the heat exchanger. In the process of designing the control algorithm, considering the strong nonlinearity, uncertainty and strong coupling of the engine, The decoupling study of the multi-input and multi-output linear model of the heat exchanger is carried out. The decoupling effect of two different decoupling methods on the strongly coupled heat exchanger is obtained. The fuzzy decoupling PID controller has short adjustment time and overshoot. Small, conclusions with better decoupling effects.

Achievements And Developments Of Hysteresis And Creep Of Pneumatic Artificial Muscles, Shenglong Xie, Haitao Liu, Jiangping Mei
Journal of System Simulation
Abstract: Regarding to the problems of hysteresis and creep, the developments and achievements of the research on pneumatic artificial muscles at home and abroad are systemically reviewed. The state of the art is summarized in terms of characteristics, reasons causing, modeling and control strategies based on the hysteresis and creep modeling. The problems in recent research are analyzed and the direction for further research is put forward. The theoretical study on hysteresis and creep of pneumatic artificial muscle is limited. The hysteresis modeling needs to consider the time-varied parameters caused by creep. Neural network modeling needs to solve …
