| Predictive control is a new type of computer algorithm appeared in the last 70's. It is based on the predictive model, and adopts online quadratic performance criteria of roll optimization and feedback correcting, which can reduce the modelling error and the uncertain effect of structure, parameters and circumstance. It has perfect control result and excellent robustness. It has achieved a great deal of successful applications in industrial process control since it appeared, and has drawn the attentions of industrial field.This paper has developed a set of predictive control software based on dynamic matrix control (DMC). The software is based on windows environment and is made up of five modules: identification, DMC algorithm, controller configuration, simulation, and real-time control.The software can identify the model of the process, and get the rangeof parameters of the controller through simulation. It also provides a common interface of ODBC, which can connect the software with configuration software so as to realize real-time control.This paper elaborates the instructions for the software through an example of simulation, and realizes the real-time DMC control for the three-section electric furnace through the integrately running of DMC controller produced by the software and ForceControl configuration software.
