Analysis And Research Of Supercritical Unit Coordinated Control System

The dynamic model of the supercritical coordinated control system is found based on the subspace identification algorithm in this paper. Through the simulation work, the validity of the dynamic model is proved. The supercritical unit has some characters such as nonlinear, parameters time-varying and large delay, predictive control has special advantage on handling target with large delay. To the question of the dynamic of supercritical unit plant coordination control system, dynamic matrix control is applied to the coordinated control system. This paper have adopted typical Centralized and decentralized control methods. A great deal of simulation work has been done, compared with the conventional PID control system. We can get the result: the control method in this paper has good control quality.
