Study on generalized predictive control of cement rotary kiln calcining zone temperature

In the process of cement production, the cement rotary kiln calcining zone temperature is the most important parameter of the whole system. The stability control of the calcining zone temperature is the key to ensure stable and reliable for the system operation. However, due to the complex operation conditions of the rotary kiln, the traditional control algorithm is difficult to achieve satisfactory control effect. In the paper, first to collect the rotary kiln calcining zone temperature by the PYROSCAN SYSTEM of HGH company, then using the least square method to identify the calcining zone temperature model that belongs to a typical operation condition, at last, applying the generalized predictive to the calcining zone temperature control. The simulation results show that the algorithm can meet the expected control requirements.
