  Electromagnetic suspension system (EMS) is mostly used in the field of
high-speed vehicle. In this paper, a space exploring vehicle quarter
electromagnetic suspension system is modelled, designed and simulated using
linear quadratic optimal control problem. Linear quadratic Gaussian and linear
quadratic integral controllers are designed to improve the body travel of the
vehicle using bump road profile. Comparison between the proposed controllers is
done and a promising simulation result have been analyzed.
