Robust Control of a Six-Degree-of-Freedom Rocket

In this article, we present a robust control program designed for a six-degree-of-freedom rocket. The program implements three advanced control algorithms: robust H-infinity control, robust loop shaping control, and mu-analysis control. Each control strategy is carefully implemented to handle uncertainties and disturbances, with H-infinity control optimizing worst-case performance, loop shaping ensuring desired frequency responses, and mu-analysis providing rigorous robust stability verification. The controllers are simulated against a high-fidelity nonlinear rocket model, allowing performance comparisons under various dynamical conditions. Our results indicate that the program delivers excellent performance across diverse scenarios, with its inherent robustness enabling effective handling of unexpected disturbances. The implementation can be further enhanced by integrating adaptive control algorithms to improve adaptability to varying environmental conditions and mission requirements. In summary, this robust control program provides significant support for the design and development of rocket control systems and holds substantial potential for future space exploration applications.
