Abstract
In this article the ride behaviour of four-wheel vehicle system with H infinity control semi-active suspension is investigated when subjected to sine and random inputs. The random inputs are represented with correlation and cross correlation functions in time domain and represented by PSD using Fast Fourier Transformation. The deterministic inputs are simple functions of specific wavelength and amplitude. The equations of motion are presented using Newtons method. It is investigated from the present analysis that proposed H infinity control semi-active suspension control is effective in isolation of vibrations at high speed.
