Studies And Simulations Of Semi-Active Vehicle Suspension System

A semi-active suspension system is considered to be one of the most realistic solutions for improving the ride quality of vehicles, because of its smaller energy consumption compared with that of active suspension systems. With applying equation of motion of a suspension, a simulation of the semi-active suspension is being done by using Simulink, MatLab. Various parameters being allocate to determine the better condition for the vehicle on different road surfaces. Fuzzy logic controller is being chosen to compute the simulation system. The basic understanding of suspension system and comparison between passive and semi-active suspension system will be shown in this report; from basic quarter model and end up with half model of suspension system.
