Active suspension controller design using MPC with preview information

The object is to develope a control law for an active suspension for the purpose of the improvement of ride characterisites. For this purpose the Model Predicitive Control methodology is applied and it is assumed that the preview information of the oncoming road disturbance is available. It is very important to consider the physical limits on the suspension travel for the vehicle running over a rough road. Thus the limits of suspension travel are accounted. Numerical simulations with the same model on the same road show that the MPC controller achieves great improvement for the ride qualities of a vehicle.
