Abstract :
An observer that decouples nonlinearity and disturbances is developed for state estimation in an active suspension. A sliding surface control law using the estimated states is implemented on a full-scale half-car suspension test rig. Control using the estimated states is shown to yield good force tracking and significant ride quality improvement at 1 Hz
