| Abstract:
This work considers a hybrid systems framework to address the guidance problem for spacecraft rendezvous, under the assumptions of the Hill-Clohessy-Wiltshire model (target spacecraft in a circular Keplerian orbit). A feedback law is designed, based on a certain Lyapunov function and the solution of an Linear Matrix Inequality, which is then robustified against noise. A realistic model is used for simulations, with the dynamics of both chaser and target being propagated through a two-body problem model and including disturbances. The robust design shows enhanced control performance against noise when compared to its non-robust counterpart. In addition, a comparative analysis with Model Predictive Control (MPC), a popular method for spacecraft rendezvous, is conducted using the Monte Carlo method, highlighting the differences with the proposed controller, namely, simplicity and ease of computation versus optimality and implicit treatment of constraints
