Development of Active Suspensions Using Velocity Feedback 960935

The application of velocity-feedback active systems to control the vehicle ride quality is studied in this paper. The control force of the active damper is derived from velocity signals, which does not need position feedback. The controller of the optimal active damper is developed from second-order equations. The control system could be used when the full-state information is not available. The power spectrum of both full-state suspension and active damping systems can be computed through a converted road roughness.
