Abstract
An extended horizon adaptive block predictive controller includes a block control system and an adaptive block prediction system. The subject adaptive block prediction system includes means and procedures for accomplishing a block of k output predictions, consisting of output predictions at each future time step up to the prediction horizon k, for dynamic systems with N outputs, M inputs and model parameter order n. The prediction system is organized for performing the calculation of a k-step ahead predictor in a highly computationally and memory efficient manner. The subject prediction system, in particular, avoids computation of a large number of the predictor parameters associated with the prior art Diophantine equation method, so that memory requirements and computational complexity are significantly reduced. The subject block control system in conjunction with an adaptive block prediction system includes means for accomplishing predictive controls of dynamic systems. It subsumes most, if not all, existing extended horizon predictive controllers. The subject block control system is based on the use of a special computational method. A hardware implementation of the subject exte…
