Visualization of Active Suspension by Robust Controller in Virtual Reality Toolbox

This paper deals with design and visualization of H-infin robust controller. It gives a brief mathematical description of physical model of suspension system of a car which was chosen as a typical example of robust control use. Therefore, first a quarter car model is introduced. Then comes the main part of solution of this problem, that is detailed design of the controller. Finally, based on real values of parameters together with a vivid visualization using a powerful environment of virtual reality toolbox, it represents a useful aid in education of modern control theory at the department of measurement and control.
