Tube Model Predictive Control for Flexible Satellite Dynamics
摘要
This chapter presents a 3-axis robust model predictive control algorithm for a flexible spacecraft during pointing maneuvers. The spacecraft’s linear system dynamics are affected by parametric model uncertainties and exogenous disturbances. In order to mitigate the effect of pointing jitters on image-capturing quality, the proposed controller creates a tube as a sequence of invariant polytopic sets, with the aim of ensuring pre-imposed bounds on the state trajectories of the system.
