Dynamic Matrix Control Based on Multi-model Synthesis and Its Application

By taking into account the practical features that the most process objects have nonlinear characteristics dependent closely on operating regime, a predictive control method based on multi-model synthesis is presented. The predictive model and the gradual optimization of the basic dynamic matrix control are improved. The method has been used in the turbidity control of coagulant dosage system of water treatment. The practical application shows that the control method is effective and brings about good control effect.
