Modeling, Analysis and PID Controller Implementation on Double Wishbone Suspension Using SimMechanics and Simulink

Abstract

This paper presents modeling of quarter car double wishbone suspension prepared by using the toolbox SimMechanics and Simulink of MATLAB software. SimMechanics uses the physical model of suspension, whereas Simulink uses the mathematical model of quarter car suspension. PID controller is then implemented on both the models to minimize the vertical body acceleration. The analysis is then carried out for various combinations of suspension parameters like spring stiffness and damping coefficient. The results for body acceleration are obtained and results of analysis of both the models are compared.
