Abstract

In this paper, a hybrid control strategy for large inertia and time delay system was proposed. The proposed hybrid control strategy combines the sampling PI control and the linear control methods together. Respectively, the sampling PI control method is used to overcome the disadvantages of the control problems which are caused by the large inertia and time delay; while the linear control method is applied to achieve stable control of the steady-state control process and improve the system robustness. Since the parameters of the linear control are varied in the control process, the fuzzy control method is utilized to get the optimal parameters so that can realize the effective control. The hybrid control strategy is implemented and practically applied to a large inertia and time delay system — cement mill in a cement plant. The practical control results illustrate that feasibility the proposed strategy both effective and implemental.
