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 verify the correctness of flight guidance system and multi-modal flight control law design under nonlinear aircraft model, a multi-modal flight simulation and verification method based on Stateflow is proposed. First of all, the flight simulation system structure frame and the six-degree-of-freedom nonlinear mathematical model are established, and the control law is designed. The guidance information is acquired in real time through the information of the planned waypoint and the flight parameters calculated by the aircraft model. Stateflow is used to complete the typical flight mode Between the logic switching, the scheduled flight path to achieve multi-modal flight simulation. The experimental results show that the system structure can be easily expanded and transplanted. This method can effectively verify the correctness of flight guidance system and control law design.
