Semi-active Vibration Control of Lateral and Rolling Motions for a Straddle Type Monorail Vehicle

Abstract

This paper is concerned with the vibration elimination of a monorail vehicle under a lateral wind load and a vertical disturbance. A nonlinear adaptive control is designed for vibration attenuation of the vehicle model by using a set of MR dampers both in the lateral and vertical directions. There are limited amount of data in literature discussing dynamic instability of the monorail vehicle under the effect of model uncertainties. The proposed adaptive controller achieves good performance in road holding and ride comfort despite uncertainties in model parameters.
