The plastic cement belongs to a polymer m ate r ia l, the chemical composition is very complex, and the work-piece is generally manufactured by compression molding. Aimed at being d if f ic u l t to control in parameters of forming process, the control strategy has been explored in this paper based on human simu-lated intelligence. It has made the anatomy in control puzzle resulted in uncertainty such as chemical com-ponent of plastic cement, summarized the characteristic of cybernetics in forming process, researched on control strategy based on human simulated intelligence, and constructed the control algorithm of forming process in plastic cement work-piece. Taking the process experiment of temperature and pressure control as an example, it has validated the good dynamic and static control quality of control algorithm constructed in this paper. The experimental results show that the control algorithm explored in this paper is reasonably available.
