Controller Design for Convoluted Air Spring System Controlled Suspension

Abstract

This paper focuses on the analysis and controlling automotive vibration using semi-active air spring suspension system by implementing fuzzy and Proportional-Integral derivative (PID) controllers for light vehicles. Due to low transmissibility coefficients and their ability to varying the force generated depends on load capacities the air spring is modelled as an actuator. The dynamic behavior of semi active actuator controlled is contrasted with passive suspension under single bump, double bump and random road profile. The performance of air spring controlled suspension has been investigated. Results show that the fuzzy controller gives optimized results.

Research on nonlinear model and fuzzy fractional order PIλDμ control of air suspension system

“…At the same time, the semi-active air suspension system of light vehicle was analyzed by fuzzy and PID control strategies. 27 Eskandary developed a mathematical model of an air suspension system with independent height and stiffness regulation. 28 By controlling the air pressure of the air chamber, the stiffness and height of the vehicle can be changed simultaneously under different driving conditions to keep the performance of the vehicle in optimal condition.…”
