The message of this simulation and optimization-based design study is threefold: first, short-distance (below 2 m) road profile preview substantially improves all relevant performance criteria of an active suspension; second, controller design for such a preview suspension can be done in a pragmatic, yet systematic way; and third, the preview (feedforward) part of the control law can co-operate harmonically with the controller of an already conceived or existing feedback-only active suspension.
