The large deadtime of plant was divided into two parts of the known and unknown ones. This division may greatly reduce the number of parameters in the Laguerre function model. An adaptive single predictive control algorithm based on the Laguerre function model was proposed. Simulation results show that this algorithm is very effective for controlling plants with large deadtime and has good robust for mismatch of the model, especially for the deadtime mismatch. The algorithm needs a few priors information only. Its computation is very simple, and it is easy to be applied in engineering.
