Abstract: In this paper, an adaptive active suspension control scheme is developed so that ride comfort becomes best at any specified location on vehicle body even if vehicle parameters are unknown. To meet this end, an ideal vehicle is designed in which the location where the ride comfort becomes best can be easily specified by setting only one design parameter. To achieve the good property also in actual vehicles with parameter uncertainties, an adaptive active suspension controller is proposed so that the actual vehicle tracks the ideal vehicle. It is shown by carrying out numerical simulations that ride comfort at any specified location can be easily improved in vehicles using the proposed adaptive active suspension controller.
