Robust controller design of a distributed transport system

The paper proposes a new design method of a distributed controller of an articulated or not transport system, composed of n units, each one driven by an asynchronous motor powered by an inverter. The proposed methodology allows to design a controller that ensures distances between the various units having generic temporal behaviors with bounded derivative and, at the same time, any speed of the head unit with bounded acceleration, despite the action of any disturbances with bounded derivative and the presence of bounded parametric uncertainties. The validity of the method is illustrated with application to an articulated transport system composed of three units.
