DESIGN OF LPV CONTROLLERS FOR ACTIVE VEHICLE SUSPENSIONS

Abstract

In the paper the linear parameter varying (LPV) method is applied to active suspensions. The suspension structure contains nonlinear components, i.e. the dynamics of the dampings and the springs. The model is augmented with weighting functions specified by the performance demands and the uncertainty assumption. By selecting scheduling parameters an LPV model is generated in which the model structure is nonlinear in the parameters but linear in the states. The design of the active suspension is illustrated in the demonstration example.
