After discussing the various principles of suspensions with variable dampers and springs mathematical models of these systems are derived. It is shown how the unknown parameters can be obtained experimentally by parameter estimation. Then two feedback principles are derived for controlling the suspension. The first controller maintains the suspension adjustment by parameter estimation and parameter control in one loop. The second controller exists of an adaptive minimum variance controller ensuring a permanent optimal performance. Experimental results are shown for suspensions on a test rig.
