摘　　要：研究飞行器制导系统实时性优化问题,由于飞行器闭环制导对于系统的实时性和制导快速性有着较高的要求,因此缺乏应用于工程实践的模型。为了能够在实验室环境下,实现飞行器闭环制导的实时仿真,提出设计闭环制导实时仿真系统。利用嵌入式系统,采用间接法求解最优制导问题。最后对系统进行了实时性测试,并对特定的吸气式高超声速飞行器模型进行轨迹仿真,结果表明,设计的系统完全能够满足飞行器闭环制导对实时性和快速性的要求。The closed-loop guidance which is still in research phase has really high demands for the real-time performance of the system and the speed performance of the guidance method,so it has not been used in practical projects.In order to accomplish the real-time simulation of flight procedure of aircraft in the laboratory environment with quite a low cost,this article elaborated the design of the real-time simulation system of closed-loop guidance, which is based on embedded system and indirect method of optimal guidance.At last,this article tested the real-time performance of the system and made a trajectory simulation of a specific hypersonic air-breathing vehicle model, which proofed that this system can completely meet the demands of the real-time performance and the speed performance for closed-loop guidance.
