Simulation and Research of Single Value Dynamic Matrix Control

Dynamic matrix control has been applied to the process of industry widely In order to improve the real time of DMC and simplify its algorithm, a new model algorithm about DMC named single value DMC is brought up,which is based on the algorithm of double value DMC. In this algorithm, only one predictive output value is chosen, while the value of control is determined by quadratic capability aim function and the output deflection is adjusted by feedback. Then the influences of each parameter on systematic performance of dynamic and static state were analyzed, and the rules of parameter choosing were given. Simulation tests show that this method has faster computing speed and better real time than the traditional DMC algorithm; and its algorithm and choosing rule are simpler than that of double value DMC; at the same time, it has good control result and good resistance of disturbance if the parameters have been chosen properly.
