Fuzzy Logic Control for active suspension of a Non-Linear Full-Vehicle Model

Abstract

This paper describes the suspension control of a seven-degree of freedom (7-DOF) non-linear full-vehicle model. The system is controlled by a fuzzy logic controller (FLC) using Skyhook theory. The proposed model takes into consideration heave, pitch and roll motions of the vehicle. Multiple road input effects on the vehicle are evaluated through simulations. The simulation results show that the developed fuzzy controller improves ride comfort without sacrificing safety.
