Аннотация:We study steering of a linear chain of point masses connected via springs to the equilibrium, by means of a bounded force applied to the first mass in the chain. In other words, we design an explicit feedback control that bring the system to a given terminal rest state in a finite time. Thus, we prove the complete controllability of the system, and describe explicitly the feedback control proposed. Then, we show its robustness with respect to unknown disturbances.
