Look-Ahead Fuzzy Logic Controller for Vehicle Suspension System

In this paper, Look-Ahead Fuzzy Logic Controller is proposed for Vehicle Suspension System (VSS). Look-Ahead Fuzzy Logic Controller introduces Grey Prediction algorithm to pre-compensate rather than post-compensate the system output error. Grey Prediction algorithm is used to predict the position output error and rate of change of error of the sprung mass. The proposed controller is simulated for Quarter Car model in MATLAB. Simulation results show that the proposed controller enhances the ride comfort of VSS when compared to Traditional Fuzzy Logic controller and passive system.
