Numerical simulations of vehicle platform stabilization

A new model for low-power active control of automotive suspension is described and numerically simulated. It is based on the vertically compressed horizontally sliding spring (VeCHSS) and is in the form of a nonlinear coupled system of ordinary differential equations. The numerical simulations indicate that when the system has one steady state, it is stable; when there are three steady states two are stable and the middle one is unstable. However, when there are two steady states, both are unstable, although the system trajectory is shown to be bounded. The simulations also indicate that the system, without any controls, can follow a periodic road profile well.
