基于DSP飞控系统的设计和实现

在军事上以及民航中,无人机已经发挥着重要的作用.随着无人机越来越广泛的应用,其性能指标和设计方法也在不断地提高.针对某型号的飞机模型,提出以DSPTMS320LF2407为处理核心并设计出飞控计算机.并以此构建了飞控系统,分别详细地对纵向、横侧向通道的控制率和算法进行设计和仿真;并实现了自主飞行,验证了以DSP设计的无人机的控制系统以及实现航路规划和管理的可行性,从而为进一步设计出高性能、高可靠性、满足更为复杂的飞行任务的无人机奠定了理论基础和硬件实现条件.

Design and Realization of Control System Based on DSP

Unmanned vehicle system(UAV) has shown its importance both in military and civil all over the world.The wider applications of UAV urge more and more universities to start the researches to enhance the UAV's performances.Based on the model of a certain type plane,a flight control computer(FCC) is designed by using the DSP(TMS320LF2407) as the core processor.Then,a half-physical flight control system is constructed.Both longitudinal and lateral control laws are respectively designed and verified in detail.Furthermore,the realization of the autonomous flight verifies the whole flight control system of the UAV and the feasibility of managing flight paths.Those verifications have provided a substantial foundation for the future UAV which meet the demands of more complexity,reliability and flexibility.
