【Abstract】 Due to its ability to hover at a stratospheric altitude of 20~30km carrying heavy payload for a long duration, the high altitude platform has an important application potential in observation, navigation and guidance, and can be widely applied to both military and civil uses. The design and implementation of the hardware-in-loop simulation system provide us a good means to recognize problems as early as possible in the developing process of high altitude platform control system. According to the characteristics and requirements of high altitude platform control system, this thesis proposes a design scheme and its implementation of the hardware-in-the-loop simulation system of a high altitude platform.First, the design of the hardware-in-the-loop simulation system of a high altitude platform is proposed. The functions of each part and operation mode are determined. The problems such as the nonlinearities in inertial measurement unit and other components, time delay properties, which cannot be accurately described, can be effectively resolved using hardware-in-the-loop simulation.Second, the thesis discusses the essential techniques and the implementation methods based on the xPC Target toolbox which is used to develop the hardware-in-loop simulation system of the high altitude platform. According to driving design principles of xPC Target, software driving of the RS-422 serial port card is designed to solve the problem of serial port communication. And a solution of the synchronization communication problem is proposed.Third, based on VC++6.0 software, console software of the high altitude platform hardware-in-loop simulation system is developed, to realize basic functions in simulation process, adjust parameters on-line, display historical curves, and display the animated simulation results. At last, the hardware-in-loop simulation system for the high altitude platform is developed. Experiments and analysis of hardware-in-loop simulation are carried on.The results show the feasibility and validity of design of the hardware-in-loop simulation system.The technique scheme proposed in the thesis characterizes generality, fast run speed, low cost and some other properties. The research in the thesis has significant application values in flight and attitude control system simulation of high altitude platforms.更多还原
