Modeling and Identification of Air Suspension in Heavy-Duty Vehicles

Modeling and Identification of Air Suspension in Heavy-Duty Vehicles

A heavy-duty vehicle can benefit from the height control of the chassis that anair suspension provides. For example, to retain a pitch angle parallel to the road,regardless of what load it carries. For the purpose of developing a controller,a model of the air suspension provides evaluation and testi...
