Comparison of landing control algorithms for vertical landing rockets in simulation environment

This study aims to comprehensively compare the performance of different landing algorithms developed for vertical landing rockets in a simulation environment. Vertical landing rockets are of great importance in space missions and other aerospace applications. The successful landing of these rockets depends on the efficiency and accuracy of the control algorithms used. The performance of the landing algorithms plays a critical role, especially in the transition from high speeds to low speeds and in the final stages of the landing. The study addresses four main control methods that affect this performance: PID control, DDPG control, and MPC control approaches. Each algorithm was subjected to various test conditions in different landing scenarios and evaluated in terms of key parameters such as accuracy, fuel efficiency, landing speed, and stability. The simulation results have identified the strengths and limitations of each algorithm, providing in-depth analyses of which algorithm performs better under specific conditions. These analyses provide significant insights for the future development of rocket landing algorithms. In particular, it has been determined which algorithm is more efficient under certain environmental conditions and which types of missions it offers ideal performance for. The findings of the study aim to contribute to making rocket technology safer, more efficient, and more cost-effective, serving as a resource for the development of landing systems for future vertical landing rockets.
