Abstract: In this paper, the linear parameter-varying (LPV) method is applied to the modelling and control of the active suspension system of vehicles. Besides the nonlinear characteristics of the suspensions, in the construction of the LPV model both the performance requirements and the model uncertainties are taken into consideration. The trade-off between the performance demands is guaranteed by using parameter dependent gains. The synthesis and the analysis of the LPV based robust control design is performed. Finally, the method is demonstrated in a quarter-car model.
Keywords: linear-parameter varying control; robust control; nonlinear modeling; uncertainty; automotive systems; active suspension system; actuator dynamics.
