摘要： The performance of a passive-levitation vehicle is improved for moving over a path, wherein the vehicle has a levitation skid slidable on the path and capable of developing a levitation force to support a compartment at a certain distance from the path. For this aim, there is a suspension, connected between the compartment and the skid, comprising a kinematic structure to confer degrees of freedom and relative constraints between the skid and the compartment; a passive elastic element connected between the skid and the compartment; and a controlled- dynamic element able to exert a force having controlled dynamics between the skid and the compartment; wherein the passive elastic element and the controlled- dynamic element being mounted in parallel to each other and connected, e.g. at their ends, respectively to the skid and the compartment. By means of a sensor the distance is detected between the skid and the path, and an electronic circuit, connected to the sensor and to the controlled- dynamics element, carries out a feedback control in order to adjust said distance.
