摘　　要：在水泥生产联合粉磨过程中,精准调控稳流仓仓重是优化辊压机预粉磨过程,降低粉磨系统能耗的关键。介绍了水泥联合粉磨系统工艺流程及辊压机稳流仓的重要作用;以稳流仓仓重为被控量、喂料量为控制量、回粉量为扰动量,建立了稳流仓仓重自抗扰智能控制系统;基于稳流仓仓重ARMAX模型,设计了稳流仓仓重自抗扰智能控制器。实验仿真表明,该控制器能够较好地跟踪稳流仓仓重设定值,仓重调控过渡平稳,抗扰动能力较强,具有无超调特性及广泛的适应性,为稳流仓仓重的精确控制开辟了新路径。In the combined grinding process of cement production,precise regulation of the stable flow bin weight is crucial for optimizing the pre-grinding process of the roller press and reducing energy consumption in the grinding system.This paper introduces the process flow of the cement combined grinding system and highlights the key role of the stable flow bin in the roller press.Taking the stable flow bin weight as the controlled variable,feeding amount as the controlling variable,and returned powder amount as the disturbance,an active disturbance rejection intelligent control system for the stable flow bin weight is established.Based on the ARMAX model of the stable flow bin weight,an auto disturbance rejection intelligent controller is designed.Experimental simulations demonstrate that the controller can effectively track the setpoint of the stable flow bin weight,with smooth transitions during weight regulation,strong disturbance rejection capability,and no overshoot,showing broad adaptability.This opens up a new path for the precise control of the stable flow bin weight.
