Abstract: An identification method is presented for the parameters of a quasi Linear Parameter Varying (qLPV) model of a quarter car suspension system where non-linear components are taken into consideration. Because not all the variables necessary for the identification are measured, some numerical techniques need to be applied, e.g., the numerical integration of measured signals. It is also shown that the selection of the sampling time might be critical in this type of application. By using the result of this identification an algorithm is given for the road disturbance reconstruction. The road roughness estimation is based on this reconstructed signal.
