Investigation of active vibration control system for trailed two-wheeled implements

Abstract

This paper presents an active vibration control (AVC) system for trailed two-wheeled implements (TTWI) equipped with high precision electronic devices. With the aim of isolating disturbance forces to the devices, a hydraulically actuated vibration control system is devised. In order to suppress vibratory motions to the body components, considering the TTWI system characteristics, a vibration control and a force tracking control strategy is adopted. As the vibration controller, the adaptive and skyhook control schemes are applied. From full order and reduced order model for the actuating module, as the tracking controller, the sliding mode control scheme is adopted regarding parameter variations. On the basis of the roll plane TTWI system model, simulation work is performed. Finally, after implementation of the experimental setup with the TTWI system and the road simulating module considering practical requirements, actual performance of the devised AVC system is evaluated in various disturbance conditions.
