Robust Transferable Sets of Linear Transferring Strategies

The problem of transferring a controlled linear system with a disturbance to a prescribed target set (a hyperplane at a prescribed time instant) is considered. The control and disturbance are subject to geometrical constraints. The original transfer problem is reduced to a scalar one. Then, for a given transferring linear feedback strategy, the respective transferable set is studied, i.e. the set of all the initial positions in the time/state plane, from which the target set is reached, respecting the control constraints, against any admissible disturbance. Necessary and sufficient conditions for the existence of the transferable set are derived, its set-theoretical properties are established, the algorithm of its boundary construction is proposed, the boundary smoothness is studied. Illustrative examples are presented.
