Abstract
A new type of algorithm to control friction of the sliding nanoarrays is proposed. This control is based on the concept of terminal attractor and is global in that it requires only the knowledge of the velocity of the center of mass and is applied globally to the whole array. The efficiency and robustness of the control by reaching a broad spectrum of target velocities-both close to or far from natural attractors-in very short transient times is demonstrated.
