Long-endurance Unmanned Aerial Vehicle Flight Control System Simulation Platform

A new convenient, high-efficiency's flight simulation platform designing method is put forward in this dissertation. It is adopted that a rapid prototype method based on Matlab/RTW (Real-Time Workshop) and Vx Works real-time operation system. These method can realize highly efficient and low cost development of highly secure flight control computer system .Firstly, in simulation flight control subsystem, the host computer use Tilcon Real-Time Developer(TRTD) to develop man-machine interface software under Windows XP operation system. This software can realize auto-code building and loading of modeh graphics displaying and parameter controlling of simulation data. This real-time developing kit have shorten time of development, transplant between different platform, strong graphics interface and real time.Secondly, in target computer a new kind of technique is used in our simulation software. Using this method which is different from extra mode of MATLAB we can realize online tuning parameters, monitoring signal and collecting data functions. Its merit is making a unique running an environment of software and making operation become convenient, decreasing the error happening.Lastly, the board support packages for the embedded real time operating system-VxWorks and driver of serial multiport card Smartio C104H in VxWorks system are designed and developed in flight control subsystem. This driver uses double buffers arithmetic to receive and deal with the data from simulation computer. It is developed that the serial communication software in treble redundancies semi-physical simulation flight control system.
