Abstract： By simplifying the drum granulation process as a two-input - two-output system, the transfer function matrix model was established. To realize automation control of drum granulation process, a dynamic matrix control algorithm was proposed for its multi-variable long time-delay characteristics. Dynamic matrix control algorithm was designed and simulated by model predictive control tool box of MATLAB software for the given operation scheme. The results show that this method can optimize the manipulated variable based on the given reference output, so that the output trajectory can be tracked effectively.
