基于结构分散化控制的球磨机制粉系统控制与仿真

Control and Simulation of Ball Mill Pulverizing System Based on Structure Distribute Control

按照球磨机制粉过程运动特性的基本因果关系,建立一种球磨机制粉过程的结构分散化模型,它由6个单元模型、3条因果链和4支链间关联的模型构成。以该模型为基础,设计球磨机制粉过程的预估系统,它拥有单元预估系统、基本关联模型和依托因果链的预估信息传递模型,保证在子系统设计预估算法,仍然能够获得对整体系统运动特性的满意预估。设计球磨机制粉过程的控制系统,它包含单元控制系统和依托因果链的控制指令传递模型,保证在子系统设计控制算法,仍然能够获得对整体系统的期望控制性能。该新型控制系统应用于球磨机制粉过程控制,具有良好的稳定性、抗干扰和容错能力。

According to the ball mill pulverizing process motion character＇s basic causality, a structure decentralized model is built which is consisted of six unit models, three causality chains and four inter - chain associations. Based on this model, predicative system and control system are designed which depended on the causes and effects chain transmit prediction information and control command. This new control system is applied in ball mill pulverizing system, the result indicates that this method possesses excellent stable characteristic, anti - jamming abilities and fault - tolerant capacity.
