Prediction of stochastically fluctuating values using the example of road surface roughness

The prediction of stochastically fluctuating values is very interesting for the control of systems with stochastically fluctuating input values. In this paper a prediction method for road surface distortion is presented. If a high prediction quality can be assured, this information can be very useful for the control of a road vehicle´s active damping. In the frame of this paper, different prediction methods were introduced and tested for their average prediction error. The most interesting prediction method is the one which is based on short term statistics.
