[Abstract]:In view of the characteristics of large lag, large inertia and nonlinearity in the operation of double-disc mill, the internal model control, as an advanced control strategy, has the advantages that the precision of the process model is not high, and so on. This paper presents a PI control method based on the principle of internal model control. The controller designed by this method has only one adjustable parameter, and the tuning is realized by the maximum sensitivity index, which effectively avoids the complexity and randomness of the controller tuning. The simulation results show that compared with conventional PID control, the proposed method can effectively reduce the influence of model parameters and various disturbances on the performance of the system, meet the requirements of the controller in the process of mechanical pulping production, and ensure the safe and stable operation of the mill. The stabilization control of mill load is realized, which lays a foundation for the implementation of the integrated automation system of mechanical pulping process.
