Development of an educational interactive hardware-in-the-loop missile guidance system simulator.

This paper presents a hardware-in-the-loop (HIL) simulator, named HIL-GSS, which aims to help the students of aerospace engineering learn control and missile guidance theories effectively by using interactive instrumentation. Electromechanical components and interactive panels are illustrated. Two case-based studies are presented to show the advantages that HIL-GSS offers to engineering education. Steady-state tracking errors of the PID controller based on the HIL-GSS are around zero. The final miss distance in the real-time HIL TV guidance engagement simulation is 0.2376m. Those results show the reliability of the proposed HIL simulator. In addition, the students' average response to survey questions is 4.22 (1-5 grade scale), which indicates that students strongly agree or agree that HIL-GSS is an effective educational tool.
