Active seat suspension based on second order inertial delay control combined with Sliding Mode Control

This paper deals with the problem of integrated active seat suspension. The control strategy is based on inertial delay control (IDC) combined with sliding mode control (SMC). The road disturbance, reflected through the sprung mass position and velocity and system uncertainties estimated in real time using IDC and compensated using the control. The proposed strategy is evaluated by simulation for two types of road disturbances. The results are compared with a passive system.
