摘　　要：制导控制半实物仿真系统在制导武器的研制中发挥着重要作用,是验证导弹制导控制系统设计和软件设计正确性的重要途径。传统的Windows操作系统实时性较差,给半实物仿真试验带来诸多不确定因素,采用Windows+RTX的方案,完成了半实物仿真系统的软硬件设计,通过共享内存实现Windows进程和RTX进程之间的通信,保证数据传输准确性和系统实时性。导弹制导控制半实物仿真试验结果表明:所设计的半实物仿真系统合理,并且实时性好、可靠性高、通用性强。The guidance and control semi physical simulation system plays an important role in the development of guided weapons,and is an important way to verify the correctness of missile guidance and control system design and software design.The traditional Windows operating system has poor real-time performance,which brings many uncertainties to the hardware in the loop simulation test.Therefore,this paper uses the Windows+RTX scheme to complete the hardware and software design of the hardware in the loop simulation system.Through shared memory,the communication between Windows processes and RTX processes is realized to ensure the accuracy of data transmission and the real-time performance of the system.The final missile guidance and control semi physical simulation test results show that the designed semi physical simulation system is reasonable,and has good real-time performance,high reliability,and strong universality.
