Circumnavigation for Underactuated Hovercrafts Using Postion Measurements
摘要
This paper addresses the target circumnavigation control problem for an underactuated hovercraft. To our knowledge, this problem has not been previously investigated for these platforms. Drawing upon cascaded systems theory, state and dynamic output feedback controllers are systematically developed to ensure global exponential stability of the nominal closed-loop system. The analysis is then extended to address more practical scenarios, proving semi-global exponential stability under input saturation and ensuring the system is practically stable in the presence of external disturbances. The effectiveness of the proposed methods is validated through numerical simulations.
