Design of a Control System for Electromagnetic Suspensions of a Heavy Vehicle Considering Torsion of a Body

Abstract

The authors focus on anti-rolling performance of a heavy vehicle, and propose to suppress the roll motion of the heavy vehicle by active control using electromagnetic suspensions. The body of the heavy vehicle is modeled as a continuous cylinder to describe torsional motion, therefore differences of roll angles of the front and the rear axis can be expressed. Then the authors design a control system to suppress the roll and torsion of the body using optimal control theory. The results of the numerical simultations and the experiments show the proposed system reduces roll angles of the torsional body better than the passive suspension system.
