This paper analyses the straight-ahead stability of a single track, free control vehicle, using a gyroscopic rolling stabilisation device. Studying the eigensolutions of a 8 degrees of freedom model (six used by the vehicle itself, one to model the driver and one for the stabilisation facility) makes clear how the control system may be effective in damping the oscillations around the vehicle longitudinal axis: at the price of a small perturbation of Yaw mode, the Cap Size mode becomes negligible, while the Weave mode gets stable in the whole speed-field.

Abstract
This paper analyses the straight-ahead stability of a single track, free control vehicle, using a gyroscopic rolling stabilisation device. Studying the eigensolutions of a 8 degrees of freedom model (six used by the vehicle itself, one to model the driver and one for the stabilisation facility) makes clear how the control system may be effective in damping the oscillations around the vehicle longitudinal axis: at the price of a small perturbation of Yaw mode, the Cap Size mode becomes negligible, while the Weave mode gets stable in the whole speed-field.
