Semi-Active Suspension System Control Using Skyhook and Groundhook Controller

Abstract

The purpose of this research paper is to analyze the effect of skyhook and groundhook control strategies on a semi-active suspension system. Computer simulation of the quarter-vehicle model is conducted through MATLAB/SIMULINK. The ride comfort and handling characteristics of the suspension system are predicted for random road input by the mathematical model. The passive suspension system performance is compared with skyhook and groundhook controlled semi-active suspension system. The result shows that the groundhook control offers better ride comfort and handling as compared to skyhook and passive suspensions. Also, the results showed in the time domain, frequency domain, power spectral density, and root mean squares values.
