Design and implementation of a hardware-in-the-loop simulation system for interceptor composite control

In order to verify the functionality of the composite control system of the interceptor, a hardware-in-the-loop simulation system was constructed, and simulation verification was carried out. Firstly, a six-degree-of-freedom dynamic mathematical model of the interceptor. Then the interceptor composite control system was designed, including a direct force control subsystem, an aerodynamic control subsystem and a composite control strategy based on the interception process analysis. We created a tiny hardware-in-the-loop simulation system and examined its confidence by looking at the hardware model, software platform, data interaction network, and system design. Lastly, the control effects of hardware-in-the-loop simulation and full digital simulation were compared under various interception scenarios. The results confirm the accuracy and efficacy of the interceptor's composite control system and demonstrate the high degree of confidence in the hardware-in-the-loop simulation system, which can be used to validate models and algorithms.
