为了验证非线性飞机模型下飞行制导系统和多模态飞行控制律设计的正确性,提出了基于Stateflow的多模态飞行仿真验证方法.首先建立了飞行仿真系统结构框架和飞机六自由度非线性数学模型,并进行控制律设计,通过预定航路点信息和飞机模型解算的飞行参数实时获得制导信息,采用Stateflow完成典型飞行模态之间的逻辑切换,实现了预定航迹多模态的飞行仿真.实验结果表明,系统结构易于扩充和移植,该方法可以有效地验证飞行制导系统和控制律设计的正确性.%In order to validate the correctness of flight guidance system and multi-mode flight control law designed in nonlinear aeroplane model,this paper proposed the method of multi-mode flight simulation based on Stateflow. First,it established the flight simulation structure frame and the 6-DOF( six degrees of freedom) nonlinear mathematical model of plane,then designed the con-trol law,obtained the information of flight guidance through setting fairway data and the flight parameters which was calculated by the nonlinear aeroplane mathematical model, the logic control of representative flight modes switch was achieved by Stateflow. And the setting fairway multi-mode flight simulation was realized. Simulation results show that the expansion and transplant of system structure are easy to realize, the method can validate the design of flight guidance system and control law effectually.
