Active and semi-active suspension control for specific point isolation of vehicles.

摘要

The concept of point control is to isolate a specified point on a vehicle body using control actuators in conventional locations within the vehicle suspension. This is done using Percussion Control and two generations of Model Reference Control, all of which are capable of reducing the motion at the control point to a negligible magnitude. The Segregated Reaction Control discussed here is most effective at achieving the task semi-actively, and improves upon Semi-Active Conventional Control for this application. At peak performance, the magnitude of absorbed power at the control point under Segregated Reaction Control was 50--70% of the magnitude under Conventional Control. When viewing a passive system as having 100% of the possible absorbed power, Segregated Reaction Control exhibited 5.7--6.9% (depending on speed) improvement over Conventional Control.
