【 摘 要 】

Considering the characteristics of large time delay and vulnerable to interference of cement particle size control. Firstly, through the rise curve of the production process to identify the transfer function with time delay by least squares algorithm. Secondly, translate the time delay system into a form of state space equation with no delay by a method of state transition. Finally, an equivalent sliding mode control is applied to control the particle size and the stability conditions of sliding mode control are given. The simulation results show it can achieve a desirable control effect in cement particle size control.
