Performance assessment and control policies for semiactive suspension using SIMSCAPE

Abstract

The semi-active suspension system utilizes a fluctuating damping power as a control force. The motivation behind this work is to examine research impact of Skyhook, Groundhook and Hybrid Control strategies of the semiactive suspension system through computer simulation of quarter-car model in MATLAB/SIMULINK (SIMSCAPE LIBRARY). The ride comfort and handling characteristics of suspension system were watched for different street profile and obstructions such as constant step input and road bump. The performance of passive suspension system model was contrasted with Skyhook, Groundhook and Hybrid controlled semiactive suspension system performance. It also states the various advantages of semi-active suspension system over the conventional suspension system. The observations and results, interpretations would be valuable for planning and designing control algorithm in development of control system.
