Abstract:To verify the key control technology of reusable vehicle, a closed-loop simulation system of reusable vehicles based on STM32 is proposed. Based on this set of platforms, the overall scheme, hardware platform design, software development and design of the system are emphasized, and the simulation of the measurement unit on the arrow, computer unit, execution unit and ground measurement, transmission and control unit is realized. The key control technologies such as guidance, navigation and attitude control algorithm of reusable vehicles have been verified through the simulation. The results show that the developed closed-loop simulation system has reasonable design, good real-time performance and high reliability. It can lay the foundation for large-scale test of reusable vehicles and shorten the development cycle.
