Abstract
This paper presents a simple technique of designing state observers for bilinear suspension models. A 2-DOF quarter-car automotive suspension is considered. The technique produces observer gains which dynamically depend on the control, and are obtained through observer pole placement in a time-varying system that uses Liapunov transformation. It is shown that the proposed use of this method could be effective in the design of modulated suspension systems, with certain limitations on the control law that is used.
