A control system, such as a vehicle management system, having a processing unit ( 20 ) and a sensor for providing data samples ( 22 ), includes a multi-step ahead predictive filter that predicts data samples based on a weighted function of prior data samples ( 26 ). This allows the system to continue to function using predicted data samples, when for example the receipt of actual data samples ( 22 ) is temporarily interrupted, e.g. due to noise, a communications fault or the like. The filter uses a single set of weights ( 28 ) for weighting the prior data samples ( 26 ), irrespective of the number of missing data samples for which the prediction is required, and the set of weights ( 28 ) is determined based on the characteristics of the sensor signal. Various methods for determining the set of weights are also disclosed.
