Testing Setup and Delay Compensation in HILS of Aerospace Systems

Abstract

Hardware In-Loop Simulation (HILS) test setup is a highly essential tool in the design and development of Aerospace vehicle subsystems. The performance evaluation of vehicle subsystems in real-time scenario helps a lot in achieving successful flight tests and minimizing the number of trials. The HILS testbed suffering from inherent delay during testing and resulted in unwanted diverging oscillations, which limits the HILS testbed effectiveness. The deep insight into the HILS testbed is presented here. The available delay compensation methods were studied, and a suitable compensation method was implemented. The adverse effectiveness of delay compensation was also discussed.
