为了使飞行器达到预定的飞行目标，需要对其飞行姿态进行控制，使飞行器能够尽可能地接近预定轨迹飞行。设计了一种由双DSP作为主控制器的飞行器飞行姿态控制系统的软件，主CPU根据预定的飞行姿态数据和GPS结合惯导的复合导航系统提供的飞行器实时姿态数据，完成姿态控制数据和飞行轨迹数据的计算，副CPU 对舵机系统进行控制。控制系统采用双DSP将数据计算和控制飞行姿态分开，控制周期较单DSP缩短了约50％，提高了响应速度。经过样机调试，实现了双DS P控制系统对飞行器飞行姿态的控制。

In order for an aircraft to reache the scheduled flight target ,its flight attitude needs to be controlled to make its flight trajectory as close to the scheduled trajectory as possible .A flight attitude control system with double DSP chips as its main controller was designed .The main CPU of the double DSP control system completed the calculation of attitude controled data and flight trajectovy data according to the aircraft’s real-time attitude data from the complex INS ( Inertial Navigation System ) w hich consists of GPS and INS and the estimated flight track data ,and the deputy CPU controled the servo system .The control system separated the data calculation from the servo system control ,which reduced the control period by 50% compared with the single DSP and improved the response speed . After the debugging of the model machine ,the control system based on double DSP can control the aircraft’s flight attitude .
